Technexion PICO-IMX7 SoM is supporting USDHC3 (eMMC or micro SD on SoM) and USDHC1 (SD on carrier board) to use on any carrier board like PICO-NYMPH. Based on the U-Boot version from Technexion it adds baseboard SD card boot detect to able to boot from selected USDHC1 or USDHC3 boot devices.

- Add baseboard SD card boot detect from Technexion's U-Boot.
- Implement board_mmc_get_env_dev() for pico-imx7d SoM.
- Implement mmc_map_to_kernel_blk() for pico-imx7d SoM.
- Add board_late_mmc_env_init() to use from common freescale
  functions to able to provide "mmcdev" and "mmcroot" variables
  in environment of U-boot.
- Add "mmc1" alias to use for usdhc1 in imx7d-pico-pi-u-boot.dtsi.
- In default environment set "mmcautodetect=yes" to use boot detection.
