Revert "x86-64/efi: Use EFI to deal with platform wall clock"
This reverts commit bacef661acdb634170a8faddbc1cf28e8f8b9eee.
This commit has been found to cause serious regressions on a number of
ASUS machines at the least. We probably need to provide a 1:1 map in
addition to the EFI virtual memory map in order for this to work.
