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.
