intel/i82801gx 82801ix: Remove OpRegion of SMBus host 

Defining this OpRegion for SMBus controller prevents linux kernel
driver i2c-i801 from registering SMBus under sysfs, with following
error in dmesg:

  ACPI Warning: SystemIO range .. conflicts with OpRegion .. (\_SB.PCI0.SBUS.SMBI)

Solution taken from intel/bd82x6x. Worth noting we do not
define ENABLE_SMBUS_METHODS anywhere currently.

Removed remaining reference to HSTS from GETAC P470.
