Add power optimization for i.MX8QM/i.MX8QX

rpi3: Remove duplicate initialization for BL32_IMAGE_ID and mark one more function as static.

Change some vars and functions to be static.

tools/fiptool: Fix UUID parsing in blob handling

Commit 03364865

 ("Make TF UUID RFC 4122 compliant") changed the scanf
parsing string to handle endianness correctly.
However that changed the number of items sscanf handles, without
adjusting the sanity check just below.

Increase the expected return value from 11 to 16 to let fiptool handle
UUIDs given as blob parameters correctly again.

Current implementation of i.MX8QX power management related
features does NOT optimize power number, all system resources
like CCI, DDR, and A cluster etc. are kept in STBY mode (powered
ON) when system suspend or CPU hotplug.

To lower the power number, OFF mode should be adopted for those
system resources whenever they can be OFF, A cluster will be OFF
if the CPUs in the cluster are all off line, DDR/MU/DB can be OFF
if system suspend, IRQ steer can be OFF if the wakeup source is
belonged to system controller partition, so wakeup source runtime
check is used to determine if IRQ steer can be OFF before system
suspend.

If resources are powered off for suspend, they should be restored
properly after system resume.

The PLAT_XLAT_TABLES_DYNAMIC build option, defined in platform_def.h
in Arm platforms, is checked by several headers, affecting their
behaviour. To avoid issues around the include ordering of the headers,
the definition should be moved to the platform's makefile.

Use full include paths like it is done for common includes.

This cleanup was started in commit d40e0e08283a ("Sanitise includes
across codebase"), but it only cleaned common files and drivers. This
patch does the same to Arm platforms.

Enable necessary A53 erratas for i.MX8QM and i.MX8MQ

When an unknown Trusty image is found, there's no point of still trying
to register the BL32 init handler. Instead, we just should bail out of
the trusty_setup() and allow the system to continue to boot.

Following changes are done to make DT pre-processing similar to that of
U-boot/Linux kernel.

1. Creating seperate CPPFLAGS for DT preprocessing so that compiler
options specific to it can be accommodated.
e.g: "-undef" compiler option avoids replacing "linux" string(used in
device trees) with "1" as "linux" is a pre-defined macro in gnu99
standard.

2. Replace CPP with PP for DT pre-processing, as CPP in U-boot/Linux is
exported as "${CROSS_COMPILE}gcc -E" while in TF-A it is exported as
"${CROSS_COMPILE}cpp".

This patch adds a platform setup handler that gets called after
the MMU is enabled. Platforms wanting to make use of this handler
should declare 'plat_late_platform_setup' handler in their platform
files, to override the default weakly defined handler.

There are Tegra platforms which have limited UART ports and so
all the components have to share the console. The SPE helps out
by collecting all the logs in such cases and prints them on the
shared UART port.

This patch adds a driver to communicate with the SPE driver, which
in turn provides the console.

This patch includes the console driver from individual platform
makefiles and removes it from tegra_common.mk. This allows future
