[ Upstream commit 6b3dd85b0b ]
pinctrl-rt2880.c and pinmux.h make up the Ralink pinctrl driver. Rename
pinctrl-rt2880.c to pinctrl-ralink.c. Rename pinmux.h to pinctrl-ralink.h.
Fix references to it. Rename functions that include "rt2880" to "ralink".
Remove PINCTRL_RT2880 symbol and make the existing PINCTRL_RALINK symbol
compile pinctrl-ralink.c. Change the bool to "Ralink pinctrl driver".
