Assert correct granularity when mapping a PA

Each translation table level entry can only map a given virtual
address onto physical addresses of the same granularity. For example,
with the current configuration, a level 2 entry maps blocks of 2 MB,
so the physical address must be aligned to 2 MB. If the address is not
aligned, the MMU will just ignore the lower bits.

This patch adds an assertion to make sure that physical addresses are
always aligned to the correct boundary.
