dm: arm: imx: cx9020: enable DM_GPIO

Switch to DM_GPIO and add gpio_request where necessary.
This is needed for DM_VIDEO and fixes an issue with sd card detection
which was introduced by the combination of these commits:

commit 7a0425dd969c ("mmc: fsl_esdhc: make get_cd work well in dm_mmc_ops")
commit 7e04b4c751a1 ("dm: arm: imx: migrate cx9020 to CONFIG_DM_MMC")
