spi: qup: Parse OPP table for DVFS support
Parse the OPP table from the device tree and use dev_pm_opp_set_rate()
instead of clk_set_rate() to allow making performance state for power
domains specified in the OPP table.
This is needed to guarantee correct behavior of the clock, especially
with the higher clock/SPI bus frequencies.
