pinctrl: renesas: rzg2l: Drop unnecessary pin configurations

Browse source

There is no need to reconfigure a pin if the pin's configuration
values are the same as the reset values.  E.g. the PS0 pin configuration
for the NMI function is PMC = 1 and PFC = 0, which is the same as the
reset values.  Currently the code is first setting it to GPIO HI-Z state
and then again reconfiguring to the NMI function, leading to spurious
IRQs.  Fix this by dropping unnecessary pin configuration from the
driver.
