efi/arm: Revert "Defer persistent reservations until after paging_init()"
Commit 582a32e708823e5957fd73ccd78dc4a9e49d21ea upstream.
This reverts commit eff896288872d687d9662000ec9ae11b6d61766f, which
deferred the processing of persistent memory reservations to a point
where the memory may have already been allocated and overwritten,
defeating the purpose.
