[PATCH 1/6] drm/bridge: imx8mp-hdmi-tx: Switch to SYSTEM_SLEEP_PM_OPS()

[Fabio Estevam]

From: Fabio Estevam <festevam at denx.de>

Replace SET_SYSTEM_SLEEP_PM_OPS with its modern SYSTEM_SLEEP_PM_OPS()
alternative.

The combined usage of pm_ptr() and SYSTEM_SLEEP_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.
