feat(debug): add helpers for aborts on AARCH32

feat(debug): add helpers for aborts on AARCH32

New helper functions are created to handle data & prefetch aborts
in AARCH32. They call platform functions, just like what
report_exception is doing.
As extended MSR/MRS instructions (to access lr_abt in monitor mode)
are only available if CPU (Armv7) has virtualization extension,
the functions branch to original report_exception handlers if this is
not the case.
Those new helpers are created mainly to distinguish data and prefetch
aborts, as they both share the same mode.
This adds 40 bytes of code.

Deprecate weak crash console functions

The default behaviour of the plat_crash_console_xxx functions isn't
obvious to someone that hasn't read all the documentation. As they are
not mandatory, it is unlikely that the code will be checked when doing a
platform port, which may mean that some platforms may not have crash
console support at all.

The idea of this patch is to force platform maintainers to decide how
the crash console has to behave so that the final behaviour isn't
unexpected.

plat/common: move arch-agnostic fallback functions to C file

When we add a new callback, we need to duplicate fallbacks among
plat/common/{aarch32,aarch64}/platform_helpers.S This is tedious.

I created a new C file, then moved 3 functions:
plat_error_handler
bl2_plat_preload_setup
plat_try_next_boot_source

They are called from C, so I do not see a good reason to implement
them in assembly.

AArch32: Miscellaneous fixes in the AArch32 code

This patch makes following miscellaneous fixes:
* pl011_console.S: Fixed the bit mask used to check if the
transmit FIFO is full or empty.
* smcc_macros.S: Added `_fsxc` suffix while updating the SPSR.
By default the assembler assumes `_fc` suffix which does not
update all the fields in SPSR. By adding `_fsxc` suffix all
the fields gets updated.
* platform_helpers.S: Removed the weak definition for
`plat_my_core_pos()` as this is a mandatory function which
needs to be defined by all platforms.

AArch32: Common changes needed for BL1/BL2

This patch adds common changes to support AArch32 state in
BL1 and BL2. Following are the changes:

* Added functions for disabling MMU from Secure state.
* Added AArch32 specific SMC function.
* Added semihosting support.
* Added reporting of unhandled exceptions.
* Added uniprocessor stack support.
* Added `el3_entrypoint_common` macro that can be
shared by BL1 and BL32 (SP_MIN) BL stages. The
`el3_entrypoint_common` is similar to the AArch64
counterpart with the main difference in the assembly
instructions and the registers that are relevant to
AArch32 execution state.
* Enabled `LOAD_IMAGE_V2` flag in Makefile for
`ARCH=aarch32` and added check to make sure that
platform has not overridden to disable it.

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.
