MIPS: Clean up tables for bootmem allocation
Modifications to the boot memory allocation structures to make them easier to read and maintain. Note that this will not pass checkpatch because it wants a structure element initializer to be enclosed in a do {...} while(...), which is obvious nonsensical.
