Several boards are using the built-in SPI controller of the AR71XX/AR724X/AR913X SoCs. This patch adds common platform_device and helper code to register it. Additionally, the patch registers the SPI bus on the PB44 board. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Cc: linux-mips@linux-mips.org Cc: Imre Kaloz <kaloz@openwrt.org> Cc: Luis R.
