pinctrl: imx: accept gpio request/free from pinctrl
While only Freescale Vybrid SoC has settings of GPIO capabilities done by iomux controller, it is only a matter of GPIO controller driver implementation for the rest of Freescale/NXP SoCs from iMX series. As a practical example on GPIO request a pad function should be switched to GPIO, but because this requires updates to all particular iMX pinctrl drivers, for simplicity at the moment add only a proper connection between shared pinctrl-imx and pinctrl/pinmux core, namely .gpio_request_enable/.gpio_disable_free/.gpio_set_direction callbacks should return success to a caller. This change allows to progress by adding request/free callbacks into gpio-mxc.c driver.
