ARM: dts: bcm2166x: Add bcm2166x-pinctrl DTSI

Add common DTSI with common pin control configs for BCM21664/BCM23550
and include it in bcm2166x-common.dtsi. The configs are kept in a
separate DTSI to keep things cleaner (pin config definitions take up
quite a lot of space).

Currently contains pins for BSC buses and SD/MMC; more pins can be
added in the future.
