[PATCH 2/2] pinctrl: renesas: rzg2l: Move pinconf_to_config_argument() call outside of switch cases

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>

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 each case of the
switch statement.
