zynqmp: pm: Reimplement clock get state (status) EEMI API
Clock get state EEMI API is reimplemented to use system-level clock and pll EEMI APIs rather than direct MMIO read/write accesses to clock and pll control registers. Since linux is_enabled method for PLLs still uses clock get state API get the PLL state, in the implementation of pm_clock_getstate() we need to workaround this by distinguishing two cases: 1) if the given clock ID corresponds to a PLL output clock ID; or 2) given clock ID is truly an on-chip clock whose state of the gate should be returned. For case 1) we'll call pm_api_clock_pll_getstate() implemented in pm_api_clock.h/c. This function will query the PLL state from PMU using the system-level PLL get mode EEMI API. For case 2) we'll call the PMU to query the clock gate state using system-level clock get status EEMI API. Functions that appear to be unused after this change is made are removed.

zynqmp: pm: Reimplement clock disable EEMI API
Clock disable EEMI API is reimplemented to use system-level clock and pll EEMI APIs rather than direct MMIO read/write accesses to clock and pll control registers. Since linux still uses clock disable API to reset the PLL in the implementation of pm_clock_disable() we need to workaround this by distinguishing two cases: 1) if the given clock ID corresponds to a PLL output clock ID; or 2) given clock ID is truly an on-chip clock that can be gated. For case 1) we'll call pm_api_clock_pll_disable() implemented in pm_api_clock.h/c. This function will reset the PLL using the system-level PLL set mode EEMI API with the reset mode argument. For case 2) we'll call the PMU to configure the clock gate. This is done using system-level clock disable EEMI API. Functions that appear to be unused after this change is made are removed.

zynqmp: pm: Reimplement clock enable EEMI API
Clock enable EEMI API is reimplemented to use system-level clock and pll EEMI APIs rather than direct MMIO read/write accesses to clock and pll control registers. Since linux still uses clock enable API to trigger locking of the PLLs in the pm_clock_enable() implementation we need to workaround this by distinguishing two cases: 1) if the given clock ID corresponds to a PLL output clock ID; or 2) given clock ID is truly an on-chip clock that can be gated. For case 1) we'll call pm_api_clock_pll_enable() implemented in pm_api_clock.h/c. This function checks what is the buffered PLL mode and calls the system-level PLL set mode EEMI API with the buffered mode value specified as argument. Long term, if linux driver get fixed to use PLL EEMI API to control PLLs, this case could be removed from ATF. For case 2) we'll call the PMU to configure the clock gate. This is done using system-level clock enable EEMI API.

zynqmp: pm: Buffer the PLL mode that is set using IOCTL API
When linux calls pm_ioctl_set_pll_frac_mode() it doesn't expect the fractional mode to be changed in hardware. Furthermore, even before this patch setting the mode which is done by writing into register takes no effect until the PLL reset is deasserted, i.e. until linux "enables" the PLL. To adjust the code to system-level PLL EEMI API and avoid unnecessary IPIs that would otherwise be issued, we buffer the mode value set via IOCTL until the PLL mode really needs to be set.

Fractional data should be set using PLL set parameter EEMI API. This stands for system-level communication (APU to PMU). Since linux already uses a specific IOCTL function to do this and we need to keep it that way, the pll clock ID given by linux has to be mapped to the pll node ID that is communicated at the system-level (argument of PLL set parameter API). With this modification the function pm_api_clk_set_pll_frac_data is removed from pm_api_clock.c/h because it became unused.

zynqmp: pm: Implement PLL set mode EEMI API
This API will be used to set the PLL mode: reset (unlocked), integer or fractional (locked). If reset mode is set the PM controller will bypass the target PLL prior to asserting the reset. If integer or fractional mode is set the PM controller will program and trigger locking of the PLL. If success status is returned the PLL is locked and its bypass is deasserted. If fractional mode is set the fractional divider (data parameter) has to have a non-zero value prior to issuing pll set fractional mode. The caller need to ensure that the data parameter is properly set using pll get/set parameter EEMI API.

Sanitise includes across codebase
Enforce full include path for includes. Deprecate old paths.
The following folders inside include/lib have been left unchanged:
- include/lib/cpus/${ARCH} - include/lib/el3_runtime/${ARCH}
The reason for this change is that having a global namespace for includes isn't a good idea. It defeats one of the advantages of having folders and it introduces problems that are sometimes subtle (because you may not know the header you are actually including if there are two of them).
For example, this patch had to be created because two headers were called the same way: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform to avoid collision."). More recently, this patch has had similar problems: 46f9b2c3a282 ("drivers: add tzc380 support").
This problem was introduced in commit 4ecca33988b9 ("Move include and source files to logical locations"). At that time, there weren't too many headers so it wasn't a real issue. However, time has shown that this creates problems.
Platforms that want to preserve the way they include headers may add the removed paths to PLAT_INCLUDES, but this is discouraged.
