[PATCH] Bluetooth: btnxpuart: Switch to SYSTEM_SLEEP_PM_OPS

[Fabio Estevam]

From: Fabio Estevam <festevam@xxxxxxx>

Replace SET_SYSTEM_SLEEP_PM_OPS() with its modern SYSTEM_SLEEP_PM_OPS()
alternative.

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

This allows removing the CONFIG_PM_SLEEP ifdefery from the
suspend/resume() functions.
