By default on startup all the pin types are configured to PINMUX_TYPE_NONE (in sh_pfc_map_pins()), when pin is set as GPIO the pin type is updated to PINMUX_TYPE_GPIO. But the type is not updated when the pin is set as a function in sh_pfc_pinctrl_pin_set() or sh_pfc_pinctrl_group_set() calls (these calls only set the MUX if the pin type is PINMUX_TYPE_NONE ie unused). So with the current implementation pin functionality could be overwritten silently, for example if the same pin is added for SPI and serial. This patch makes sure of updating pin type after every successful call to sh_pfc_config_mux() and thus fixing from pin functionality to be overwritten. Also a warning message is printed if the current pin is being overwritten before abort. This also avoids pin re-muxing to same type that is for example from command line device is asked to re-probe/select (mmc dev x) we return early with success in this case as the pin is already muxed.
