The bit locations indicating the locking status of the plls on rk3066 are
shifted by one to the right when compared to the rk3188, bits [7:4] instead
of [8:5] on the rk3188, thus indicating the locking state of the wrong pll
or a completely different information in case of the gpll.

The recently introduced pll init code exposed that problem on some rk3066
boards when it tried to bring the boot-pll value in line with the value
from the rate table.

Fix this by defining separate pll definitions for rk3066 with the correct
locking indices.
