Prepare for reducing duplicates for 4op FM related codes

Add and correct bunch of presets
- mostly based on MAME source.
- Neo Geo AES uses slightly difference clock for NTSC, PAL colorbust frequency.
- Turbosound FM + SAA: Some Turbosound FM has additional SAA1099, for additional sound channel and Plays SAM coupe tune?
- PC-98:
 - Sound Orchestra: OPN with hardpanned stereo, some model has with OPL family FM addons.
   V variation has Y8950 and supports ADPCM.
 - Sound Blaster 16 for PC-9800: This famous PC sound card is also exists for PC-98, with optional OPN PC-9801-26(K) compatibility on some models.
- IBM PCjr: PC with SN PSG sound, but less popular than previous models, and compatible Tandy 1000.
- Tandy 1000: PCjr and previous IBM PC compatible, also has SN PSG (later embedded in their ASIC, like Sega).
- Hexion: One of konami's budget arcade hardware with SCC + MSM6295 sound system, like their amusement hardware in this era.
- DJ Boy, Atari JSA IIIs, Skimaxx: How to panning sound or plays stereo sound on MSM6295 - just use MSM6295s per each output!
- Air Buster: One of arcade hardware with OPN + MSM6295 sound system, Used this configuration is also some hardwares.
- Tecmo system: One of arcade hardware with pretty unique sound system: OPL3, YMZ280B, MSM6295; first 2 entry is mostly used in music, last entry is mostly used in sound effect.
- Sunsoft Shanghai 3: Predecessor of Sunsoft Arcade is using YM2149 rather than FM, MSM6295 is still there.
- Atari Klax: example of arcade hardware sound system with single MSM6295 only.
- Ikari warriors: This early SNK Triple-Z80 hardware uses 2 OPL1s and no ADPCM supports.
- Coreland Cyber Tank: This rare arcade machine's stereo sound is like SB Pro, but it's actually produced in 2 Y8950s.
- Data East MLC: Latest arcade hardware from Data East, with single YMZ280B for sound.
- Kaneko Jackie Chan: Predecessor of Super Kaneko Nova System hardware, also with YMZ280B.
- Super Kaneko Nova System: Latest arcade hardware from Kaneko, with single YMZ280B for sound. this announced 3D acceleration addon, but finally cancelled.
- Toaplan 1: Home of Late 80-Early 90s Good ol' stuffs, Example of arcade sound system with single OPL2
- Namco Pac-Land: and this era, Namco start to change Custom 15 WSG to their Custom 30 WSG with featured RAM based waveform, and mailbox feature.
- Namco System 1: One of latest usage of Custom 30 WSG, with OPM FM hardware and 8 bit DAC and Stereo output.

Add various clock, type options for chips
- SN7: Prepare to add 17 bit noise variation, Game gear stereo extentsion, NCR PSG variation (MAME core only for now)
- OPN, OPNA: Add placeholder for prescaler option
- OPL: Prepare for OPL3L, OPL4 downscaled output rate option
