[PATCH v6 01/11] iio: adc: ti-ads1015: use DEFINE_RUNTIME_DEV_PM_OPS()

[Archit Anant <architanant5@gmail.com>]

Replace the deprecated SET_RUNTIME_PM_OPS() with
DEFINE_RUNTIME_DEV_PM_OPS().

This also configures the system sleep PM operations to use the
runtime suspend and resume callbacks, ensuring that the device
is properly suspended and resumed during system sleep transitions.

The new macro also handles dropping unused functions when
CONFIG_PM is disabled, eliminating the need for explicit
preprocessor conditionals.
