Subject: [PATCH 04/14] iio: adc: rzg2l_adc: Switch to RUNTIME_PM_OPS() and pm_ptr()

From: Claudiu Beznea <claudiu.beznea.uj@...renesas.com>

The use of SET_RUNTIME_PM_OPS() is now deprecated and requires
__maybe_unused annotations to avoid warnings about unused functions.
Switching to RUNTIME_PM_OPS() and pm_ptr() eliminates the need for such
annotations because the compiler can directly reference the runtime PM
functions, thereby suppressing the warnings. As a result, the
__maybe_unused markings can be removed.
