Ok, I'll update the commit description to below:
Refactor the `rzg2l_pinctrl_pinconf_set()` function by moving the call to
`arg = pinconf_to_config_argument(_configs[i])` to the beginning of the
loop. Previously, this call was redundantly made in most cases within the
switch statement.

And while at it I'll replace as above and below in the v2.
