gpio: mpc8xxx: add support for MPC5125
The gpio controller on MPC5125 is identical to the MPC5121 register wise, the only difference is that the lines 0..3 are input only instead of 28..31 on MPC5121. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
