[PATCH 2/2] usb: chipidea: ci_hdrc_tegra: Switch to RUNTIME_PM_OPS()

[Fabio Estevam <festevam@gmail.com>]

From: Fabio Estevam <festevam@denx.de>

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

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

This allows removing the __maybe_unused notation from the runtime
suspend/resume() functions.
