Subject: [RFC PATCH 04/13] pinctrl: renesas: pinctrl-rzg2l: Allow more bits for pin configuration

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

The pin configuration bits have been growing for every new SoCs being
added for the pinctrl-rzg2l driver which would mean updating the macros
every time for each new configuration. To avoid this allocate additional
bits for pin configuration by relocating the known fixed bits to the very
end of the configuration.
