KVM: arm64: selftests: Ensure pending interrupts are handled in arch_timer test
Break up the asm instructions poking daifclr and daifset to handle
interrupts. R_RBZYL specifies pending interrupts will be handle after
context synchronization events such as an ISB.
Introduce a function wrapper for the WFI instruction.
