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.

This patch adds AArch32 support for FVP and implements common platform APIs
like `plat_get_my_stack`, `plat_set_my_stack`, `plat_my_core_cos` for AArch32.
Only Multi Processor(MP) implementations of these functions are considered in
this patch. The ARM Standard platform layer helpers are implemented for
AArch32 and the common makefiles are modified to cater for both AArch64 and
AArch32 builds. Compatibility with the deprecated platform API is not
supported for AArch32.

This patch adds platform helpers for the new GICv2 and GICv3 drivers in
plat_gicv2.c and plat_gicv3.c. The platforms can include the appropriate
file in their build according to the GIC driver to be used. The existing
plat_gic.c is only meant for the legacy GIC driver.
In the case of ARM platforms, the major changes are as follows:
1. The crash reporting helper macro `arm_print_gic_regs` that prints the GIC CPU
interface register values has been modified to detect the type of CPU
interface being used (System register or memory mappped interface) before
using the right interface to print the registers.
2. The power management helper function that is called after a core is powered
up has been further refactored. This is to highlight that the per-cpu
distributor interface should be initialised only when the core was originally
powered down using the CPU_OFF PSCI API and not when the CPU_SUSPEND PSCI API
was used.
3. In the case of CSS platforms, the system power domain restore helper
`arm_system_pwr_domain_resume()` is now only invoked in the `suspend_finish`
handler as the system power domain is always expected to be initialized when
the `on_finish` handler is invoked.
