Subject: [PATCH v8 10/10] MIPS: mobileye: eyeq5: add pinctrl node & pinmux
function nodes
Pins on this platform have two functions: GPIO or something-else. We
create function nodes for each something-else based on functions.
UART nodes are present in the platform devicetree. Add pinctrl to them
now that the pin controller is supported.
