rk3288: Allow board-specific APLL (CPU clock) settings
This changes the API to rkclk_configure_cpu() such that we can pass
in the desired APLL frequency in each veyron board's bootblock.c.
Devices with a constrainted form facter (rialto and possibly mickey)
will use this to run firmware at a slower speed to mitigate risk
of thermal issues (due to the RK808, not the RK3288).
BUG=chrome-os-partner:42054
BRANCH=none
TEST=amstan says rialto is noticably cooler (and slower)
