One nasty part of ATF is some of boolean macros are always defined
as 1 or 0, and the rest of them are only defined under certain
conditions.

For the former group, "#if FOO" or "#if !FOO" must be used because
"#ifdef FOO" is always true.  (Options passed by $(call add_define,)
are the cases.)

For the latter, "#ifdef FOO" or "#ifndef FOO" should be used because
checking the value of an undefined macro is strange.

Here, IMAGE_BL* is handled by make_helpers/build_macro.mk like
follows:

  $(eval IMAGE := IMAGE_BL$(call uppercase,$(3)))

  $(OBJ): $(2)
          @echo "  CC      $$<"
          $$(Q)$$(CC) $$(TF_CFLAGS) $$(CFLAGS) -D$(IMAGE) -c $$< -o $$@

This means, IMAGE_BL* is defined when building the corresponding
image, but *undefined* for the other images.

So, IMAGE_BL* belongs to the latter group where we should use #ifdef
or #ifndef.

We have lots of duplicated defines (and comment blocks too).
Move them to include/plat/common/common_def.h.

While we are here, suffix the end address with _END instead of
_LIMIT.  The _END is a better fit to indicate the linker-derived
real end address.

This patch support single core to boot to Linux kernel
through Trusted Firmware.
It also support 32 bit kernel and 64 bit kernel booting.

This patch migrates the upstream platform makefiles to include the
console drivers from the new location in ARM Trusted Firmware code
base.

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.

Refactor MediaTek platform common code for further mt6795 upstream.

This patch moves the definition for `plat_get_syscnt_freq()`
from arm_bl31_setup.c to arm_common.c. This could be useful
in case a delay timer needs to be installed based on the
generic timer in other BLs.
This patch also modifies the return type for this function
from `uint64_t` to `unsigned long long` within ARM and other
platform files.

It is up to the platform to implement the new plat_crash_print_regs macro to
report all relevant platform registers helpful for troubleshooting.

plat_crash_print_regs merges or calls previously defined plat_print_gic_regs
and plat_print_interconnect_regs macros for each existing platforms.

NOTE: THIS COMMIT REQUIRES ALL PLATFORMS THAT ENABLE THE `CRASH_REPORTING`
BUILD FLAG TO MIGRATE TO USE THE NEW `plat_crash_print_regs()` MACRO. BY
DEFAULT, `CRASH_REPORTING` IS ENABLED IN DEBUG BUILDS FOR ALL PLATFORMS.

In mt8173, there are totally 10 non-cpu mtcmos, so we cannot tell
if SPM finished the power control flow by 10 status bits of PASR_PDP_3.
So, extend PASR_PDP_3 status bits from 10 to 20 so that we can
make sure if the control action has been done precisely.

The debug prints used to debug translation table setup in xlat_tables.c
used the `printf()` standard library function instead of the stack
optimized `tf_printf()` API. DEBUG_XLAT_TABLE option was used to enable
debug logs within xlat_tables.c and it configured a much larger stack
size for the platform in case it was enabled. This patch modifies these
debug prints within xlat_tables.c to use tf_printf() and modifies the format
specifiers to be compatible with tf_printf(). The debug prints are now enabled
if the VERBOSE prints are enabled in Trusted Firmware via LOG_LEVEL build
option.

The much larger stack size definition when DEBUG_XLAT_TABLE is defined
is no longer required and the platform ports are modified to remove this
stack size definition.

The PL011 TRM (ARM DDI 0183G) specifies that the UART must be
disabled before any of the control registers are programmed. The
PL011 driver included in TF does not disable the UART, so the
initialization in BL2 and BL31 is violating this requirement
(and potentially in BL1 if the UART is enabled after reset).

This patch modifies the initialization function in the PL011
console driver to disable the UART before programming the
control registers.

Register clobber list and documentation updated.
