Subject: [PATCH v2 03/11] pinctrl: renesas: rzg2l: Move arg and index in the main function block

From: Claudiu Beznea <claudiu.beznea.uj@...renesas.com>

Move arg and index in the main block of the function as they are used by
more than one case block of switch-case (3 out of 4 for arg, 2 out of 4
for index). In this way some lines of code are removed.

Signed-off-by: Claudiu Beznea <claudiu.beznea.uj@...renesas.com>

Changes in v2:
- adapted for index variable and updated patch title and description
  accordingly
