[PATCH] gpio: GPIO_SAMA5D2_PIOBU should depend on ARCH_AT91

From: Geert Uytterhoeven
Date: Mon Jul 11 2022 - 07:14:01 EST

The SAMA5D2 PIOBU is only present on some AT91/Microchip SoCs. Hence
add a dependency on ARCH_AT91, to prevent asking the user about this
driver when configuring a kernel without AT91/Microchip SoC support.

Say yes here to use the PIOBU pins as GPIOs.
