inteltool: Model 0xf2x, ICH5, i865 support.

Add support for dumping the MSRs on model_f2x and dumping GPIOs and PM
registers on ICH5. Add ICH5 and i865 to the supported chips list.
Enable the dumping of BAR6 on i865.

Sample output:

  Disabling memory access:
  $ sudo setpci -s 6.0 0x04.b=0x0
  
  $ sudo ./inteltool -m | head -n 9
  Intel CPU: Processor Type: 0, Family f, Model 2, Stepping 7
  Intel Northbridge: 8086:2570 (i865)
  Intel Southbridge: 8086:24d0 (ICH5)
  
  ============= MCHBAR ============
  
  Access to BAR6 is currently disabled, attempting to enable.
  Enabled successfully.
  BAR6 = 0xfecf0000 (MEM)
