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.

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.

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.

Introduce utils.h header file ...

This patch introduces a new header file: include/lib/utils.h.
Its purpose is to provide generic macros and helper functions that
are independent of any BL image, architecture, platform and even
not specific to Trusted Firmware.

For now, it contains only 2 macros: ARRAY_SIZE() and
IS_POWER_OF_TWO(). These were previously defined in bl_common.h and
xlat_tables.c respectively.

bl_common.h includes utils.h to retain compatibility for platforms
that relied on bl_common.h for the ARRAY_SIZE() macro. Upstream
platform ports that use this macro have been updated to include
utils.h.

zynqmp: pm: Added NODE_IPI_APU slave node ID in pm_defs.h ...

NODE_IPI_APU is the node ID of APU's IPI device. If APU should be

the wake-up source upon suspend.

zynqmp: Add bakery_lock to protect APU_PWRCTRL register access ...
