In order to move all architecture pinmux into a more accurate place which is 'drivers/pinctrl/ralink' we have to first of all move this file also there with a small modification which creates 'rt2880_pinmux_init' function to allow SoCs pinctrl drivers to pass its configuration to the common code located in 'pinctrl-rt2880.c' file.
