It is quite simple for these buses. Subtract 0x20000000 from MX51 
address and you have the MX53 address. MX53 has some additional 
peripherals, but otherwise the common peripherals are all at the same 
relative offsets. A 3rd MX5 derivative also has the same memory map as 
MX53 with slightly different peripheral mix.
