[PATCH v4 1/8] iio: adc: ti-ads1015: use DEFINE_RUNTIME_DEV_PM_OPS()

[Archit Anant <architanant5@gmail.com>]

Replace the deprecated SET_RUNTIME_PM_OPS() with the modern
DEFINE_RUNTIME_DEV_PM_OPS() macro. This allows for the removal of the
macro automatically handles dropping unused functions when PM is
disabled.

Update the driver struct to use pm_ptr() to avoid unused variable
warnings.
