The rework of the PM support has caused two functions to
be orphaned when CONFIG_PM is disabled:

media/i2c/smiapp/smiapp-core.c:1352:12: error: 'smiapp_power_off' defined but not used [-Werror=unused-function]
media/i2c/smiapp/smiapp-core.c:1206:12: error: 'smiapp_power_on' defined but not used [-Werror=unused-function]

This changes all four PM entry points to __maybe_unused and
removes the #ifdef markers for consistency. This avoids the
warnings even when something changes again.

Fixes: cbba45d43631 ("[media] smiapp: Use runtime PM")
