Naomi improvements [Samuele Zannoli]

Browse Source 
This patch implements a "plug-in board" device for the Naomi.
It represents the rom boards for the various games and the dimm board for the gdrom.

Now the dimm board part contains only a routine to load the "rom file" from the gdrom chd, but in the future it will be fully implemented with its own sh4 processor, security chip and so on.

Extracted .rom files are no longer needed, rom file is extracted in code from the CHD.


(needs a little cleanup as it was based on pre-aaron 'change everything' code, but it's functional)

Naomi ROM board info from ElSemi:
NAOMI_ROM_OFFSETH = 0x5f7000,
NAOMI_ROM_OFFSETL = 0x5f7004,
NAOMI_ROM_DATA = 0x5f7008,
NAOMI_DMA_OFFSETH = 0x5f700C,
NAOMI_DMA_OFFSETL = 0x5f7010,
NAOMI_DMA_COUNT = 0x5f7014,
NAOMI_COMM_OFFSET = 0x5F7050,
NAOMI_COMM_DATA = 0x5F7054,
NAOMI_BOARDID_WRITE = 0x5F7078,
NAOMI_BOARDID_READ = 0x5F707C,
each port is 16 bit wide, to access the rom in PIO mode, just set an offset in ROM_OFFSETH/L and read from ROM_DATA, each access reads 2 bytes and increases the offset by 2.
the BOARDID regs access the password protected eeprom in the game board. the main board eeprom is read through port 0x1F800030
To access the board using DMA, use the DMA_OFFSETL/H. DMA_COUNT is in units of 0x20 bytes. Then trigger a GDROM DMA request.
Dimm board registers (add more information if you find it):

NAOMI_DIMM_COMMAND = 5f703c 14000014 (16 bit):

bit 14-9: 6 bit command number (naomi bios understands 0 1 3 4 5 6 8 9 a)
bit 7-0: higher 8 bits of 24 bit offset parameter
NAOMI_DIMM_OFFSETL = 5f7040 14000018 (16 bit):
