sb/intel/i82801ix: Add common code to set up LPC IO decode ranges
This does the following:
- Add gen[1-4]_dec options to the devicetree to set up generic LPC
decode ranges in the southbridge code.
- Move setting up some default decode ranges to a common place. If
somehow a board needs to override this behavior it can happen in the
mb_setup_superio() hook (that will be renamed when moving to
C_ENVIRONMENT_BOOTBLOCK).
