Finley Xiao 211ccb244c PM / devfreq: rockchip_dmc: Fix low voltage when probe 
If initial rate is greater than opp rate and initial voltage isn't qeual
to opp volatge, the opp voltage may too low for initial rate, so it's
inappropriate to update voltage when initial voltage isn't qeual to
opp volatge.

In order to solve this problem and consider that the regulator is shared
between several devices on some platforms, make the following two changes.

If the driver doesn't support to change frequency, the opp table should
contain an opp whose rate is geater than or equal to initial rate, so that
the voltage is enough for initial rate and the min_uV and max_uV of
regulator aren't equal to zero after update voltage.

If the driver supports to change frequency, let devfreq framework update
rate and voltage.
