This patch does some general cleanup in the Rockchip clock code, and
adds some more assertions regarding the PLL VCO and output frequency
ranges. It changes all PLL divisors to use the lowest values that can
still hit the target frequency, since higher NR values lead to higher
jitter and higher NO values increase power draw.
Also change DDR3 frequency code to hardcode the optimal divisors for
certail frequencies. As a little hack we will interpret 666000000 to
actually mean 666666666.6P (and analogous for 533MHz), since that's what
you usually want for memory.
