ARM: PSCI: Split out common stack setup code from psci_arch_init
Every platform has the same stack setup code in assembly as part of
psci_arch_init.
Move this out into a common separate function, psci_stack_setup, for
all platforms. This will allow us to move the remaining parts of
psci_arch_init into C code, or drop it entirely.
Also provide a stub no-op psci_arch_init for platforms that don't need
their own specific setup code.
