arm64: Kconfig: drop unneeded dependency on OF_GPIO for ARCH_MVEBU

[PATCH v3] arm64: Kconfig: drop unneeded dependency on OF_GPIO for ARCH_MVEBU

Posted by Bartosz Golaszewski 1 month, 2 weeks ago

OF_GPIO is selected automatically on all OF systems. Any symbols it
controls also provide stubs so there's really no reason to select it
explicitly. ARCH_MVEBU already selects GPIOLIB, drop the redundant
OF_GPIO dependency.
