MIPS: Move several variables from .bss to .init.data

Several static uninitialized variables are used in the scope of __init
functions but are themselves not marked as __initdata.  This patch is to put
those variables to where they belong and to reduce the memory footprint a
little bit.

Also, a couple of lines with spaces instead of tabs were fixed.
