PCIe supports multiple data rates that may operate at the same clock
frequency by varying the link width. In such cases, frequency alone
is insufficient to identify the correct OPP. Use the newly introduced
dev_pm_opp_find_freq_level_exact() API to match both frequency and
level when selecting an OPP, here level indicates PCIe data rate.
