mm/memblock.c: remove unnecessary log and clean up

Commit Message

Miles Chen Jan. 18, 2017, 6:16 a.m. UTC

There is no variable named flags in memblock_add() and memblock_reserve()
so remove it from the log messages.
This patch also cleans up the type casting for phys_addr_t by using
%pa to print them.
