zynqmp: pm: Call set_wakeup_source for all wake devices on sys-suspend
During system suspend, identify slaves which are configured
as wake sources and call pm_set_wakeup_source API for each of them.
zynqmp: pm: Call set_wakeup_source for all wake devices on sys-suspend
During system suspend, identify slaves which are configured
as wake sources and call pm_set_wakeup_source API for each of them.
Identifying if device may wake the system is done by checking if any
interrupt of that device is enabled in GICD_ISENABLER when the APU is
about to enter SUSPEND_TO_RAM state. If such interrupt is found,
pm_set_wakeup_source is called with corresponding PM node ID as
argument.

The state argument of the pm_self_suspend API encodes the state to

zynqmp: pm: Provide state argument to the pm_self_suspend API call
The state argument of the pm_self_suspend API encodes the state to
which the APU intends to suspend. The state can be:
- PM_APU_STATE_CPU_IDLE - processor power down, all memories remain
on
- PM_APU_STATE_SUSPEND_TO_RAM - all processors powered down, L2$
powered down, all OCM banks in retention and DDR in
self-refresh.
The calls for setting requirements for L2$ and OCM banks are now
redundant and removed.

DEFINE_BAKERY_LOCK() macro is used to put lock in coherent memory region.
ARM Trusted Firmware design guide, chapter 11 states that bakery_lock data
structures should be allocated in coherent memory region because it is
accessed by multiple CPUs with mismatched shareability, cacheability and
memory attributes.
