This patch enable convert DM MMC for imx7d-pico board and variant.
Before the DM conversion only usdhc3 was enabled and therefore it appeared
as MMC 0 to u-boot. After enabling MMC DM though usdhc3 defaults to MMC 2,
which left unattended would drive changes to existing pico-pi bootscripts and
environment variables that rely on mmc 0.
Setup the alias of mmc0 and usdhc3 so that existing pico-imx7d boot code will
work unmodified.
When converting to DM_MMC it is necessary that SPL initializes eMMC
by itself, so move the original eMMC initialization from U-Boot
proper to SPL.
