[PATCH] env: ti: boot: Fix Android boot on AM57x EVM

[Sam Protsenko]

When applying DTBO on top of DTB (with "fdt apply" command) on AM57x EVM
board, there is not enough memory reserved in RAM for DTB blob. Hence,
DTBO can't be merged in DTB. It leads to inability to boot Android with
next error message:

    failed on fdt_overlay_apply(): FDT_ERR_NOSPACE

To overcome that issue let's provide 1 MiB of space to keep DTB and all
merged DTBO blobs. To do so, "length" parameter should be specified for
"fdt addr" command:

    => fdt addr $fdtaddr 0x100000

Also add size variables to 'adtimg' command invocations, to avoid
cluttering the console with DTBO blob sizes.
