8dc7b2ef36 SCAT chipset improvements : 
- Implemented ROMCS enable feature.
- Fixed RAM write protect register setting wasn't properly applied.
- Implemented Encoded RAS mode emulation on 82C235 revision A and 82C386 chipset.
- Implemented of experimental memory bank interleaved addressing emulation on
  82C836 chipset and removed hardcoded memory configuration setting. KMX-C-02's
  BIOS now automatically detects DRAM configuration and set DRAM configuration
  register value correctly.
- Improved accuracy of 82C235 chipset's memory bank addressing. GW-286CT GEAR
  BIOS now set DRAM configuration register correctly when Dynamic Memory Resizing
  is enabled.
- Changed Award286 clone and Samsung SPC-4200P's chipset revision to rev A.
- SCAT revision D chipset now set high ROM mapping size to 128KB.
