[PATCH] sunxi: dts: add a note that memory size is adjusted by boot loader.

[Ian Campbell]

I had to spend a couple of minutes proving to myself that this was the case on
cubietruck, so add a comment to save the next guy some effort.

This patch applies cleanly against v3.13 and Hans' sunxi-devel branch.

A plausible alternative would be to pull the memory node out of the dtsi files
and into the board specific files. I didn't go straight to that since I'd have
to research all the various boards ;-)

I considered maing it "reg = <0 0>" but decided that having some sort of least
common denominator would let things work even if the bootloader were broken.
