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.
