fix(mediatek): support saving/restoring GICR registers

The GICR_IPRIORITYR[x] registers are not saved or restored in the
original design. When the kernel tries to use them, such as the
pseudo-NMI, it leads crashes and freezes. This patch adds support for
saving/restoring GICR registers.

feat(mt8188): add devapc setting of apusys rcx

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.

Moreover, apusys ao devapc must be set after apusys power init, so
we need to place the drivers in TF-A instead of coreboot.

feat(aarch64): add stack debug information to assembly routines

Debugging assembly is painful as it is, and having no useful stack trace
does not help. Code must emit CFI directives whenever the stack moves to
enable stack traces. Otherwise, the layout of the stack frame is
ambiguous, the debugger gives up, and shows nothing. The compiler does
this automatically for C but not assembly.

Add this information to the (currently unused) func_prologue macro.
