Fix DMG-on-CGB issue with LCDC bit 0 introduced in #27. See here for info on the difference in behavior between "Non-CGB Mode" and "CGB Mode" addressed by this PR. (Our previous DMG-on-CGB fixes focused primarily on functionality enabled by the CGB bootrom, and may have missed other functional differences along these lines.)
Additionally, this testrom should now demonstrate the same behavior on CGB as it does on DMG.
