cv1k.cpp: found and corrected bad bits in Pink Sweets U2 graphics roms based on comparison 4 dumped versions [MetalliC, rtw]

Browse Source 
notes: pinkswtsb (2006/04/06 MASTER VER.) and pinkswtsx (2006/xx/xx MASTER VER.) uses same U2 graphics content with 1 bad bit difference in pnkswtsb_u2.
normally after manual changes in roms BAD_DUMP flag must be raised, but here we have 4 dumps with almost identical contents (only two 128kb files different/changed from oldest to latest version), so 99.9% with these changes we have full good Pink Sweets U2 nand dumps now.
sad stats: 4 dumps, 2 of them was a bit bad, i.e. 50% cases - so bad quality components was used by Cave in theirs 'expensive' SH3 PCBs...
