mfd: rk808: Add register caching
Let's define the voltatile registers (those that can't be cached) and
enable caching. The rk808 is accessed almost constantly with cpufreq
so this is really nice.
As measured by ftrace:
before this change: cpu0_set_target() => ~2200us
after this change: cpu0_set_target() => ~500us
