[WIP] add i945G based mainboard

82945GC - 82801Gx - W83627EHG
CPU:
 CPUID 0f65.Mmicrocode loaded correctly.
DDR2:
 Supports Up to 4 DIMM.
S3:
 working properly.

Issues:
 1) It will not boot when using RAM 533MHz.
    I believe that there is a problem with time/clock or
    something related to clock when RAM 533 is used.
 2) It will not boot if channel 0 is not populated at all.
 3) HWM is not working. The FAN is running at high speed.
