x86/cpu: Remove LASS restriction on EFI

x86/cpu: Remove LASS restriction on EFI

The initial LASS enabling has been deferred to much later during boot,
and EFI runtime services now run with LASS temporarily disabled. This
removes LASS from the path of all EFI services.

Remove the LASS restriction on EFI config, as the two can now coexist.
