This patch defines common Armada 370 pinctrl settings for uart0 and
uart1 interfaces:
uart0: MPP0-1 as default
uart1: MPP41-42 as default
Note: this patch has the potential to break out-of-tree users w/o
specific pinctrl settings for their uart interfaces if the default
above does not match their config.
