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. Tested on a generic i12-tvbox with 32 bit bus-width / 1G RAM, and on a qt840a with 16 bit bus-width / 512M RAM.
