[PATCH v2 4/7] mips: Remove savemaxmem parameter setup

From: Zhang Yanfei <zhangyanfei at cn.fujitsu.com>

saved_max_pfn is used to know the amount of memory that the previous
kernel used. And for powerpc, we set saved_max_pfn by passing the
kernel commandline parameter "savemaxmem=".

The only user of saved_max_pfn in mips is read_oldmem interface.
Since we have removed read_oldmem, so we don't need this parameter
anymore.
