From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>
Simplify the `riic_i2c_probe()` function by using the
`devm_reset_control_get_optional_exclusive_deasserted()` API to request a
deasserted reset line. This eliminates the need to manually deassert the
reset control and the additional cleanup.
