qemu: don't use C functions for the crash console callbacks

Use the console_pl011_core_* functions directly in the crash console
callbacks.

This bypasses the MULTI_CONSOLE_API for the crash console (UART1), but
allows using the crash console before the C runtime has been initialized
(eg to call ASM_ASSERT). This retains backwards compatibility with respect
to functionality when the old API is used.

Use the MULTI_CONSOLE_API to register UART0 as the boot and runtime
console.

Clean usage of void pointers to access symbols

Void pointers have been used to access linker symbols, by declaring an
extern pointer, then taking the address of it. This limits symbols
values to aligned pointer values. To remove this restriction an
IMPORT_SYM macro has been introduced, which declares it as a char
pointer and casts it to the required type.

Remove sp_min functions from plat_common.c

This patch removes default platform implementations of sp_min
platform APIs from plat/common/aarch32/plat_common.c. The APIs
are now implemented in `plat_sp_min_common.c` file within the
same folder.

The ARM platform layer had a weak definition of sp_min_platform_setup2()
which conflicted with the weak definition in the common file. Hence this
patch fixes that by introducing a `plat_arm_` version of the API thus
allowing individual boards within ARM platforms to override it if they
wish to.

Emit warnings when using deprecated GIC init

Emit runtime warnings when intializing the GIC drivers using the
deprecated method of defining integer interrupt arrays in the GIC driver
data structures; interrupt_prop_t arrays should be used instead. This
helps platforms detect that they have migration work to do. Previously,
no warning was emitted in this case. This affects both the GICv2 and GICv3
drivers.

Also use the __deprecated attribute to emit a build time warning if these
deprecated fields are used. These warnings are suppressed in the GIC
driver compatibility functions but will be visible if platforms use them.

Improve MULTI_CONSOLE_API deprecation warnings

For platforms that have not migrated to MULTI_CONSOLE_API == 1, there
are a lot of confusing deprecated declaration warnings relating to
use of console_init() and console_uninit(). Some of these relate to use
by the generic code, not the platform code. These functions are not really
deprecated but *removed* when MULTI_CONSOLE_API == 1.

This patch consolidates these warnings into a single preprocessor warning.
The __deprecated attribute is removed from the console_init() and
console_uninit() declarations.

For preprocessor warnings like this to not cause fatal build errors,
this patch adds -Wno-error=cpp to the build flags when
ERROR_DEPRECATED == 0.
This option (and -Wno-error=deprecated-declarations) is now added to
CPPFLAGS instead of TF_CFLAGS to ensure the build flags are used in the
assembler as well as the compiler.

This patch also disentangles the MULTI_CONSOLE_API and ERROR_DEPRECATED
build flags by defaulting MULTI_CONSOLE_API to 0 instead of
ERROR_DEPRECATED. This allows platforms that have not migrated to
MULTI_CONSOLE_API to use ERROR_DEPRECATED == 1 to emit a more meaningful
build error.

Finally, this patch bans use of MULTI_CONSOLE_API == 1 and AARCH32, since
the AArch32 console implementation does not support
MULTI_CONSOLE_API == 1.
