common/block/fast_spi: Add extended BIOS window as reserved region 

The fast SPI driver reports the BIOS window as reserved so that the OS
is aware of this region. Now that platforms which supports an extended
BIOS window are added to this driver, add the extended range as reserved
as well if it is enabled. And since this is now handled in the SPI
driver itself, remove the extended BIOS region reporting from
common systemagent code.
