Are there others SoCs that need an update because they're using an OPP table? Doesn't this need to come after the driver change?

Kernel clock driver assumes that initial rate is the max rate for that clock and was not allowing it to scale beyond the assigned clock value. drop the assigned clock rate property and set it during resume sequence with max value in the opp table.
