mpc85xx: tlb.c cleanups
Extract the operation to read a tlb into a function - we will need this later to print out the tlbs, and there's no point in duplicating the code. Create a TSIZE_TO_BYTES macro to deal with the conversion from the MAS field to an actual size instead of duplicating this in code. There are a few misc other minor cleanups.
