Subject: [PATCH] pinctrl: renesas: rzg2l: Suppress binding attributes

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

Suppress binding attributes for the rzg2l pinctrl driver, as it is an
essential block for Renesas SoCs. Unbinding the driver leads to warnings
from __device_links_no_driver() and can eventually render the system
inaccessible.

Fixes: c4c4637eb57f ("pinctrl: renesas: Add RZ/G2L pin and gpio controller driver")
