[PATCH] PA-RISC MM init fixes

 - add missing header fixing build warning
From: Thibaut Varene <varenet@parisc-linux.org>

 - remove duplicate definition of max_pfn
From: Randolph Chung <tausq@parisc-linux.org>

 - remove unnecessary assignment to mem_map (thanks to Dave Hansen)
 - print memory in MB, not Mb
