media: imx-jpeg: Switch to RUNTIME/SYSTEM_SLEEP_PM_OPS()

Commit Message

From: Fabio Estevam <[e-mail]>

Replace SET_RUNTIME_PM_OPS()/SET SYSTEM_SLEEP_PM_OPS() with their modern
RUNTIME_PM_OPS() and SYSTEM_SLEEP_PM_OPS() alternatives.

The combined usage of pm_ptr() and RUNTIME_PM_OPS/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 CONFIG_PM ifdefery from the runtime
suspend/resume() functions.
