mmc: fsl_esdhc: make GPIO support optional
There would be compiling error as below when enable driver model for esdhc. undefined reference to `dm_gpio_get_value' undefined reference to `gpio_request_by_name_nodev' This patch is to make GPIO support optional with CONFIG_DM_GPIO. Because all boards of QorIQ platform don't need it and they just check register for CD/WP status, only some boards of i.MX platform require this.
