[U-Boot] [PATCH] sunxi: Drop qt840a_defconfig

[Hans de Goede]

The qt840a is one of the many tv-boxes using the "i12" A20 pcb, but it
populates only one of the 2 places for a 16 bit dram ic, thus reducing
the buswidth to 16 bits, and the amount of ram to 512M, which is why we
had a separate config for it.

This commit switches the generic i12-tvbox_defconfig over to DRAM
autoconfiguration, so that it will work with the qt840a too, and drops the
qt840a specific config, like we've done with other memory-amount specific
configs before.
