soc/intel/common/graphics: Add new Kconfig SOC_INTEL_DISABLE_IGD
This SOC_INTEL_DISABLE_IGD Kconfig will allow to skip IGD
initialization using FSP GOP and eventually disable the IGD.
TEST=Able to get depthcharge pre-OS splash screen when mainboard
user selects SOC_INTEL_DISABLE_IGD with below HW/FW/SW
configuration:
HW: ADLRVP + AMD Radeon RX 5700 PCI-E DGPU
FW: coreboot with depthcharge as payload for ADLRVP and OpRom for
AMD PCI-E DGPU
SW: Chrome OS RC10 release
