Apusys rcx is a subsys in apusys, and it is a basic domain of APU and
it connects several components in APU.
The devapc control of apusys rcx is also inside APU and it can only be
set when APU is powered on.
Then apusys kernel driver will trigger rcx devapc init by ATF smc call.

Apusys ao devapc is a set of control registers inside APU, and it
controls the access permission of APU ao domain.
Moreover, apusys ao devapc must be set after apusys power init, so
we need to place the drivers in TF-A instead of coreboot.

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.
