After DM conversion, the size of U-Boot binary to increase.
Previous size is 480K after DM Conversion the new size is 557K
So it's necessary to increase the dfu request for store u-boot-dtb.img in eMMC.

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.

Currently $loadaddr and $fdt_addr_r point to the same address. This
might be not ideal for some distro boot scripts which make use of
$loadaddr after loading the device tree.

Make sure the two variables point to two different addresses. Moving
$loadaddr is not entirly trivial since it is defined in mx6_common.h.
Move $fdt_addr_r and $ramdisk_addr_r by 1MiB, which should be enough
for scripts.
