payloads/external/SeaBIOS: Allow setting buffers below 0xC0000
Add the option to coreboot to set the SeaBIOS buffers below 0xC0000.
This is a requirement on the Intel Rangeley processor
because it is designed so that only the processor can write
the higher memory areas. This prevents USB and SATA from bus-mastering
into the buffers when they're set in the typical 0xE0000 area.
This will be set to Y unless defaulted to N by the mainboard or
chipset.
Push the SeaBIOS buffers down to 0x90000 segment for Mohon Peak
