    Update amd/south_station/fadt.c with various fixes
    
    This is a model fadt.c that I would like to use for updating
    several other AMD platforms with after acceptance.
    
    - Updated to match ACPI 3.0b specification and added comments
      to reflect that.
    - Since smi_cmd is 0, remove commands that rely on it:
      acpi_enable, acpi_disable, & pstate_cnt
      Add comments to that effect.
    - Changed preferred_pm_profile to SOHO Server (platform
      specific)
    - The southstation platform is legacy free - Updated
      iapc_boot_arch and flags to reflect that.
    - Added reset_register flag so that operating systems
      will actually use the reset_reg.  This is important
      on legacy free systems.
    - Updated Generic Address Structures to use access_size
      name in the updated acpi.h.  Added access sizes to
      the structures where reasonable.
    - Removed 64-bit x_firmware_ctl pointer to facs.  This was
      causing a fwts failure and windows-64 BSOD.
    - Added bit width for pm2_cnt_blk and modified gpe0_blk bit
      to match the hardware.
