soc/intel/icelake: Add option to enable display over PCI external GFX

This patch updates required FSP UPDs to get display either

Also creates a new kconfig option to bring display over external
PCI based GFX card. CONFIG_HAVE_EXT_GFX to select all required kconfig
to launch legacy oprom from pci based GFX card.
