[PATCH 07/12] x86/efi: Clean up a minor mistake in code comment

From: Baoquan He <bhe@redhat.com>

EFI allocate runtime services regions from EFI_VA_START, -4G, down
to -68G, EFI_VA_END, 64G altogether. The mechanism was introduced in
commit d2f7cbe7b26a7 ("x86/efi: Runtime services virtual mapping").

Clean it up to avoid confusion.
