Rename Kconfig options for secmon and spintable to be prefixed with
ARM64_ instead of ARCH_, which seems to be the standard throughout the
rest of coreboot (e.g. ARM_LPAE or X86_BOOTBLOCK_SIMPLE). I think this
provides a clearer separation between generic options that are selected
by the architecture (e.g. a hypothetical ARCH_HAS_FEATURE_X similar to
some of the MAINBOARD_HAS_... we have) and options that only make sense
in the context of a single architecture.

GICv2 provides a wake IRQ/FIQ (for wake-event purpose), which are not
disabled by GIC CPU interface. This is done by adding a bypass override
capability when the interrupts are disabled at the CPU interface. To
support this, there are four bits about IRQ/FIQ BypassDisable in CPU
interface Control Register. So the CPU can exit from WFI when an
asserted IRQ is coming. This is critical for power gating a CPU.
