[PATCH] x86, efi: print debug values in Kib not MB

[Prarit Bhargava <prarit@redhat.com>]

The current debug print in EFI does

[    0.000000] efi: mem84: type=3, attr=0xf, range=[0x00000000645b5000-0x00000000645fb000) (0MB)

and rounds off the size to 0MB and isn't very useful.  We should print this in
Kib.  After applying this patch we get better info with

[    0.000000] efi: mem84: type=3, attr=0xf, range=[0x00000000645b5000-0x00000000645fb000) (280kiB)
