Heyi Guo ac9b530e6b ArmPkg/TimerDxe: Add ISB for timer compare value reload
If timer interrupt is level sensitive, reloading timer compare
register has a side effect of clearing GIC pending status, so a "ISB"
is needed to make sure this instruction is executed before enabling
CPU IRQ, or else we may get spurious timer interrupts.
