serial: msm: select PM_OPP

Commit 173ebdedcd ("serial: msm: Use OPP table for DVFS support")
made the MSM serial driver unconditionally configure the core clock
through the OPP framework during probe.

When CONFIG_PM_OPP is disabled, devm_pm_opp_set_clkname() is a stub that
returns -EOPNOTSUPP, so every MSM serial port fails to probe. Select
PM_OPP to keep minimal configurations functional.
