David VomLehn 59dfa2fcae MIPS: PowerTV: Streamline access to platform device registers
Pre-compute addresses for the basic ASIC registers. This speeds up access
and allows memory for unused configurations to be freed. In addition,
uninitialized register addresses will be returned as NULL to catch bad
usage quickly.
