pm_service ipi functions can be used by other xilinx
platforms. So move it to common directory. Also change
node_id member type in pm_proc structure so it can be
used for versal where device IDs are used instead of
node IDs.
To accommodate this change header files are re-organized.

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: e0ea0928d5 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a2 ("drivers: add tzc380 support").
This problem was introduced in commit 4ecca33988 ("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.

Beside standard suspend-to-RAM state, Zynq MPSoC supports
suspend-to-RAM state with additional power savings, called
power-off suspend-to-RAM. If this mode is set, only NODE_EXTERN
must be set as wake source. Standard suspend-to-RAM procedure
is unchanged.
This patch adds support for setting suspend mode from higher
ELs and ensuring that all conditions for power-off suspend mode
are set.

This fix modifies the order of system includes to meet the ARM TF coding
standard. There are some exceptions to this change in order to retain
header groupings and where there are headers within #if statements.

Replace all use of memset by zeromem when zeroing moderately-sized
structure by applying the following transformation:
memset(x, 0, sizeof(x)) => zeromem(x, sizeof(x))
As the Trusted Firmware is compiled with -ffreestanding, it forbids the
compiler from using __builtin_memset and forces it to generate calls to
the slow memset implementation. Zeromem is a near drop in replacement
for this use case, with a more efficient implementation on both AArch32
and AArch64.

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
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.

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.
