[PATCH v4 0/2] Fix Aligned Page Allocation For XHCI

["Ashish Singhal" <ashishsingha@nvidia.com>]

This patch set is an attempt to fix the error where we allocate incorrectly
aligned memory for XHCI PEI and DXE. The change for DXE phase has been verified
already but change for PEI needs to be verified by Hao as I do not have a
setup to be able to verify that.

The change in DXE just updates a parameter passed in to allocate aligned memory.
The change in PEI adds a new function to allocate aligned memory. There was no
need to add separate function to free aligned pages as unaligned pages have been
already freed during allocation function and the aligned one can be freed using
the existing function.
