As part of migrating to DM_GPIO and DM_PINCTRL, eventually we will remove the asm/arch/gpio.h header. In preparation, clean up the various files that include it. Some files did not contain any GPIO code at all, so this header was completely unused. A few files contained only legacy platform-specific GPIO code for setting up pin muxes. They were left unchanged, as that code will be completely removed by the DM_PINCTRL migration. The remaining files contain some combination of DM_GPIO and legacy GPIO code. For those, switch to including asm/gpio.h (if it wasn't included already). Right now, this header provides both sets of functions, because ARCH_SUNXI selects GPIO_EXTRA_HEADER. This will still be the right header to include once the DM_GPIO migration is complete and GPIO_EXTRA_HEADER is no longer needed.
