clk: imx: imx8mp: Switch to RUNTIME_PM_OPS()

Replace SET_RUNTIME_PM_OPS() with its modern alternative RUNTIME_PM_OPS().

The combined usage of pm_ptr() and RUNTIME_PM_OPS() allows the
compiler to evaluate if the suspend/resume() functions are used at
buid time or are simply dead code.

This fixes the following s390 allmodconfig build errors:

drivers/clk/imx/clk-imx8mp-audiomix.c:363:12: error:
