Subject: [PATCH 1/2] Remove EFI memmap quirk for UV

Commit a5d90c923bcf ("x86/efi: Quirk out SGI UV") added a quirk to
efi_apply_memmap_quirks to force SGI UV systems to fall back to the old
EFI memmap mechanism.  We have a BIOS fix for this issue now, so we no
longer need this quirk in the kernel.  This commit removes the quirk
from the function in question.
