Subject: [PATCH] arch-arm: Provide default mask for raz/rao helpers

Rather than forcing raz registers to write something like:

.raz(uint64_t(-1))

we provide a shorter version where if
no bitmask is specified we assume the entire register is
raz/rao. This won't be probably used by rao but I
am striving for symmetry and providing a default won't
probably hurt
