On Raspberry Pi platform GPIO controller also responsible for pins multiplexing. Pi code predates proper FDT support in FreeBSD so a lot of pinmux info is hardcoded. This patch: - Implements pinctl methods in bcm2835_gpio - Converts all devices with ad-hoc pinmux info to proper pin control mechanisms and adds pinmux info in FreeBSD's custom dts files. - Adds fdt_pinctrl option to RPI2 and RPI-B kernels - Adds SPI pinmux config to FreeBSD's customization of GNU DTS.
