Modified Files:
        src/sys/arch/aarch64/include: locore.h
        src/sys/arch/arm/include: cpufunc.h
        src/sys/arch/arm/pic: pic_splfuncs.c

Log Message:
Add DISABLE_INTERRUPT_SAVE(), like DISABLE_INTERRUPT() but also returns
the previous state.

Use DISABLE_INTERRUPT_SAVE()/ENABLE_INTERRUPT() in pic_splfuncs instead
of cpsid()/cpsie(). The difference here is the caller no longer specifies
which bits to disable and enable; on arm32 we continue to use I32_bit and
on aarch64 we now consistently toggle both IRQ and FIQ state.
