arm: ti: boot: Increase system partition size

Android code base is growing, so since Android "Pie" the size of
system.img grew up to be about 740 MiB. Let's increase system.img to
1 GiB to accommodate for those changes and leave some margin for future
changes. We don't want to make it more than 1 GiB, because we should
keep userdata partition big enough (for user files, like media etc.),
and eMMC size on BeagleBoard-X15 is only 3.5 GiB.

Commit a2b96ece5be146f4995d737f047e5bbb76079b8f breaks the enumeration

This is a sync with kernel mainline dts.

The U-Boot eMMC does not need to care about the power for Rockchip
SoCs, because if the board is using eMMC, the power will default on
(for bootrom), so the 'vmmc', 'vqmmc' is only useful for SD in U-Boot.
