Refactor console_flush() and console_switch_state(CONSOLE_FLAG_RUNTIME)
to bl31_main(). This has been done per the recommendation in TF-A
mailing list. These calls need to be the last calls, after any runtime
initialization has been done, before BL31 exits.
All platforms that override the generic implementation of
bl31_plat_runtime_setup() have been refactored. The console_flush()
and console_switch_state() calls have been removed as they become
part of bl31_main() function.
Any platform that don't need to make any change to the generic (weak)
implementation of bl31_plat_runtime_setup() don't need to override it
in their platforms.

Flush the FIFO before switching to runtime. This is so that there are
no lingering chars in the FIFO when we move to the runtime console.
TF-A plans to refactor the console_Switch_state(CONSOLE_FLAG_RUNTIME)
and console_flush() calls and make them the last calls in bl31_main()
(before BL31 exits). Until then they are being left as the last calls
in bl31_plat_runtime_setup() for testing before refactoring.
This patch affects the Mediatek platform only.

Remove the use of SMC_RET2 in the mtk_emi_mpu_sip_handler function. The
current smc driver in the atf driver has switched to using SMC_RET4 for
smc call clients. This change aligns the return value handling with the
updated driver behavior that ensures consistency and avoids potential
issues with the old return value.

So far we have the ENABLE_AMU build option to include AMU register
handling code for enabling and context switch. There is also an
ENABLE_FEAT_AMUv1 option, solely to protect the HAFGRTR_EL2 system
register handling. The latter needs some alignment with the new feature
scheme, but it conceptually overlaps with the ENABLE_AMU option.
Since there is no real need for two separate options, unify both into a
new ENABLE_FEAT_AMU name in a first step. This is mostly just renaming at
this point, a subsequent patch will make use of the new feature handling
scheme.

Some of our specialized sections are not prefixed with the conventional
period. The compiler uses input section names to derive certain other
section names (e.g. `.rela.text`, `.relacpu_ops`), and these can be
difficult to select in linker scripts when there is a lack of a
delimiter.
This change introduces the period prefix to all specialized section
names.
BREAKING-CHANGE: All input and output linker section names have been
prefixed with the period character, e.g. `cpu_ops` -> `.cpu_ops`.

This change allows platforms to provide more than one linker script to
any image utilizing the `MAKE_BL` build system macro.
This is already done by some MediaTek platforms via the
`EXTRA_LINKERFILE` build system variable, which has now been removed.
In its place, additional linker scripts may be added to the
`<IMAGE>_LINKER_SCRIPT_SOURCES` variable.
BREAKING-CHANGE: The `EXTRA_LINKERFILE` build system variable has been
replaced with the `<IMAGE>_LINKER_SCRIPT_SOURCES` variable. See the
commit message for more information.

Compiling with -Wimplicit-fallthrough=3 (enabled by -Wextra) produces
many warnings about fallthrough comments either missing or being wrong.
Unify the comments so we comply with -Wextra.
Note that Coverity recommends against using the __attribute__ directive.
Also, zlib does not build with a higher value of -Wimplicit-fallthrough.
Finally, compilers strip comments before expanding macros. As such,
checkpatch's fallthrough annotation (or higher levels of the flag) isn't
really possible.
