[U-Boot] [PATCH 1/3] arm: am57xx: Define Android partition table

"fastboot oem format" command reuses "gpt write" command, which in turn requires correct partitions defined in $partitions variable. This patch adds such definition of Android partitions for DRA7XX EVM board.
By default $partitions variable contains Linux partition table. In order to prepare Android environment one can run next commands from U-Boot shell:
=> env set partitions $partitions_android => env save
After those operations one can go to fastboot mode and perform "fastboot oem format" to create Android partition table.
While at it, enable CONFIG_RANDOM_UUID to spare user from providing UUIDs for each partition manually.

OK, lets not add that in, it's not going to be viable long-term anyhow.
