[MULTIBOOT2 DOC PATCH v3 01/13] multiboot2: Replace u_phys with u32

[Daniel Kiper <daniel.kiper@oracle.com>]

u_phys is used just in two places and sometimes it may confuse reader.
Additionally, GRUB multiboot2 implementation does not use u_phys anywhere.
So, replace it with basic well defined and used in implementation u32 type.
