Add support for an optional reset control to the RZN1 A5PSW driver.
Obtain the reset line using
devm_reset_control_get_optional_exclusive_deasserted() during probe
to ensure that the Ethernet switch (ETHSW) block is properly released
from reset before initialization.

This change prepares the driver for use on Renesas RZ/T2H and RZ/N2H
SoCs, where the ETHSW IP block is connected to a dedicated reset line
that must be controlled by software.
