efi/arm*: Stop printing addresses of virtual mappings
With the recent %p -> %px changes, we now get something like this in
the kernel boot log on ARM/arm64 EFI systems:
Remapping and enabling EFI services.
EFI remap 0x00000087fb830000 => (ptrval)
EFI remap 0x00000087fbdb0000 => (ptrval)
EFI remap 0x00000087fffc0000 => (ptrval)
The physical addresses of the UEFI runtime regions will also be
printed when booting with the efi=debug command line option, and the
virtual addresses can be inspected via /sys/kernel/debug/efi_page_tables
(if enabled).
So let's just remove the lines above.
