pinctrl: ralink: add new compatible strings for each pinctrl subdriver

As seen on any other pinctrl subdriver that calls code from a main driver,
each subdriver needs to have a different compatible string. We don't want
the same compatible string to match a different subdriver's pinmux data as
it's not for our SoC.

Therefore, add new compatible strings for each pinctrl subdriver. Change
driver name on all subdrivers accordingly.
