printf: remove %pGt support
Patch series "Increase the number of bits available in page_type".
Kent wants more than 16 bits in page_type, so I resurrected this old patch
and expanded it a bit. It's a bit more efficient than our current scheme
(1 4-byte insn vs 3 insns of 13 bytes total) to test a single page type.
This patch (of 4):
An upcoming patch will convert page type from being a bitfield to a
single byte, so we will not be able to use %pG to print the page type
any more. The printing of the symbolic name will be restored in that
patch.
