In ITLB miss handled the line supposed to clear bits 20-23 on the
L2 ITLB entry is buggy and does indeed nothing, leading to undefined

Properly do the clearing with the relevant instruction.

With HW assistance all page tables must be 4k aligned, the 8xx
drops the last 12 bits during the walk.
Redefine HUGEPD_SHIFT_MASK to mask last 12 bits out.
HUGEPD_SHIFT_MASK is used to for alignment of page table cache.
