rockchip: close the PD center logic during suspend

The RK3399 supports close the center logic enter power mode,
so we can close PD_CENTER to save more power during suspend.
Therefore, we need to support save/restore the DDR PHY and
controller registers during suspend/resume.

Also, need CL (http://crosreview.com/397399) to check disabling
center logic.

This renames dram.c and dram.h to dfs.c and dfs.h respectively. This

rockchip: clear the power mode status via M0

Due to the PMU design, the PMU may not clear the WAKEUP bit after
wakeup, therefore, the state machine at the power mode may enter
the infinite loop during WFI.

There is a solution that we can use the M0 to monitor the WAKEUP
bit and clear it during power mode, then the state machine will be
recovered immediately. Then, the DUT can exit the WFI normally.

1) Add the new file to handle the pwm. (e.g. the pwm regulator)
Make sure that good deal with the pwm related things.
Also, remove some pwm setting for pmu.c.

2) Set the plls slow mode and bypass in suspend, and restore them.

2. Save and restore the PWMs pin/regs for suspend/resume.
3. The pmusgrf reset-hold bits needs to be released. since the
pmusgrf reset-hold bits needs to be held.
4. Configure the PMU power up/down cycles about delay 3ms.
5. With the MMIO register block as one big mapping.
6. Fix the build error with psci_entrypoint since PSCI lib updated.

Fixes the commit

Support for Rockchip's family SoCs

This patch adds to support the RK3368 and RK3399 SoCs.

RK3368/RK3399 is one of the Rockchip family SoCs, which is an
multi-cores ARM SoCs.

This patch adds support to boot the Trusted Firmware on RK3368/RK3399
SoCs, and adds support to boot secondary CPUs, enter/exit core
power states for all CPUs in the slow/fast clusters.

This is the initial version for rockchip SoCs.(RK3368/RK3399 and next SoCs)
* Support arm gicv2 & gicv3.
* Boot up multi-cores CPU.
* Add generic CPU helper functions.
* Support suspend/resume.
* Add system_off & system_reset implementation.
* Add delay timer platform implementation.
* Support the new porting interface for the PSCI implementation.
