mfd: as3722: Mark PM functions as __maybe_unused
The newly introduced as3722_i2c_suspend/resume functions are built
unconditionally, but only used when power management is enabled,
so we get a warning otherwise:
drivers/mfd/as3722.c:427:12: warning: 'as3722_i2c_suspend' defined but not used [-Wunused-function]
drivers/mfd/as3722.c:438:12: warning: 'as3722_i2c_resume' defined but not used [-Wunused-function]
This marks them both as __maybe_unused, which avoids an ugly #ifdef
and gives us best compile-time coverage. When they are unused, the
compiler will silently drop the functions from its output.
