The driver data specific to each pinctrl GPIO bank compatible nodes are not
the same and declaring additional compatible string as fallback has no
specific purpose, hence, removing the "atmel,at91sam9x5-gpio" compatible from
sam9x60 SoC DT.

Note: The at91 pinctrl driver uses "atmel,at91rm9200-gpio" compatible string
to find the number of active GPIO banks and identify the pinmux nodes.It
should used as a constant across all DT for GPIO node banks that uses PIO3
based pinctrl driver

Applied to at91-dt, thanks!
