Soren Brinkmann 8787c0e00c zynqmp: Make MMIO write FW call synchronous
We must guarantee that writes have become effective before returning to
the caller. Hence, wait for PMUFW signaling completion of the FW call
before returning to the rich OS.

Filip Drazic b516b7dc5d 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.

Filip Drazic 95fd990fe6 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.
