Fixed layer enable,flip x & x/y position in goodejan.c driver [Angelo Salese]

Browse Source 
=============

Several Seibu games (i.e. D-Con,sdgndmps,Sengoku Mahjong,goodejan/totmejan and the raiden2.c/legionna.c games) all have a standard 0x48 (0x50?) 
regs-wide C.R.T.C. 

I wonder if it is a custom Seibu crap or a known video chip,would be good if somebody can do tests on it. For sure,it should be abstracted,this 
commit was made by looking mostly at Sengoku Mahjong.
