rockchip/rk3399: Move big CPU cluster initialization into ramstage

This patch moves the big CPU cluster initialization on the RK3399 from
the clock init bootblock function into ramstage. We're only really doing
this to put the cluster into a sane state for the OS, we're never
actually taking it out of reset ourselves... so there's no reason to do
this so early.

Also cleaned up the interface for rkclk_configure_cpu() a bit to make it
more readable.

BRANCH=None
BUG=chrome-os-partner:54906
TEST=Booted Kevin.
