mips: remove savemaxmem parameter setup

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.
