sb/intel/i82801gx: Select INTEL_HAS_TOP_SWAP
The i82801gx southbridge has the ability to swap the two top 64K ranges by
flipping the BUC.TS bit (RCBA[3414] bit0)
This effectively means it is possible to run another bootblock located at
top_of_flash - 64K.
This allows coreboot to build roms with a bootblock at the top swap offset by
selecting CONFIG_INTEL_ADD_TOP_SWAP_BOOTBLOCK.
