The sev() and wfe() asm macros are currently defined only for
mach-exynos. As these are common Arm instructions, move them to the
common asm/system.h header file, for both Armv7 and Armv8, so they
can be used by other machines.
wfe may theoretically trigger a context switch if an interrupt occurs
so add a memory barrier to this call.
