Ard Biesheuvel 0487cac09f ArmPkg/ArmMmuLib: Disable and re-enable MMU only when needed
When updating a page table descriptor in a way that requires break
before make, we temporarily disable the MMU to ensure that we don't
unmap the memory region that the code itself is executing from.

However, this is a condition we can check in a straight-forward manner,
and if the regions are disjoint, we don't have to bother with the MMU
controls, and we can just perform an ordinary break before make.
