Pre-Seibu CRTC update: [Angelo Salese]

Browse Source 
* Fixed gfx banking in goodejan/totmejan;
* Fixed vertical scrolling in Sengoku Mahjong (check title screen);
* Made some clean-ups in either drivers;

==================================================

The (likely) custom Seibu CRTC is used at least in the following games:
Raiden (probably the first game to use it)
Sengoku Mahjong
Good e Jong
Tottemo de Jong
Blood Bros.
Sky Smasher
D-Con
SD Gundam Psycho Salamander no Kyoui
(all games in legionna.c)
(all games in raiden2.c)

All of these games have 4 layers with 2048 (0x800) bytes of ram each,a palette ram with xRRRRRGGGGGBBBBB format and (at least) 72 (0x48) video registers.
The idea here is to merge everything in a single file and to understand the issues with some of them,namely the "bitmap_fill" color (goodejan/totmejan 
needs a black pen on the service mode and a white-to-black fade out effect at start-up?),some kludges with the tilemaps/sprites positioning (in both 
sd gundams,sdgndmsp and sdgndmrb for example) plus obviously anything that isn't yet understood from these regs.
