pinctrl: renesas: rzg2l: Suppress binding attributes

[ Upstream commit ea40653 ]

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.
