28f9035732 ARM: PSCI: Remove unused psci_text_end symbol
psci_text_end was used to calculate the PSCI stack address following the
secure monitor text. Now that we have an explicit secure stack section,
this is no longer used.

b52813239c 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.
