pinctrl: ralink: move ralink architecture pinmux header into the driver
Ralink architecture is making use of the header located in
'arch/mips/include/asm/mach-ralink/pinmux.h' to stablish the
mechanisms to make derived SoCs to set its pin functions and
groups. 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.
