Although the GPC provides the similar functions for all the
i.MX8M SoC family, the HW register offset and bit defines
still have some slight difference, so move the hw reg
offset & most of the bitfield defines in 'gpc_reg.h' that
is specific to each SoC.

This patch moves all GICv3 driver files into new added
'gicv3.mk' makefile for the benefit of the generic driver
which can evolve in the future without affecting platforms.
The patch adds GICv3 driver configuration flags
'GICV3_IMPL', 'GICV3_IMPL_GIC600_MULTICHIP' and
'GICV3_OVERRIDE_DISTIF_PWR_OPS' described in
'GICv3 driver options' section of 'build-option.rst'
document.

NOTE: Platforms with GICv3 driver need to be modified to
include 'drivers/arm/gic/v3/gicv3.mk' in their makefiles.

This patch provides separation of GICD, GICR accessor
functions and adds new macros for GICv3 registers access
as a preparation for GICv3.1 and GICv4 support.
NOTE: Platforms need to modify to include both
'gicdv3_helpers.c' and 'gicrv3_helpers.c' instead of the
single helper file previously.

Since now the generic console_t structure holds the UART base address as
well, let's use that generic location and drop the UART driver specific
data structure at all.

The manual documents that 0x3036006c should contains the soc revision
for imx8mq but this always reports A0. Work around this by parsing the
ROM header and checking if OCOTP register 0x40 is stuck at 0xff0055aa.

Determining this inside TF-A makes life easier for OS, see for example
this linux discussion: https://lkml.org/lkml/2019/5/3/465

The soc revision can also be useful inside TF-A itself, for example for
the non-upstream DDR DVFS "busfreq" feature is affected by 8mq erratas.

The clock for OCOTP block can be disabled by OS so only initialize soc
revision once at boot time.

Besides, the .console_flush callback needs to be added to avoid

call it without checking whether the function callback is valid.

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: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a282 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca33988b9 ("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.
