soc/skl: set IGD resources only if device is enabled
If the Intel IGD device pci 02.0 is disabled or undefined in the device tree, then internal graphics pre-allocated memory and GFX-VT MMIO memory for virtualization won`t be allocated in the SoC address space. Thus, patch resolves the FSP-S hang problem on Skylake/ Kaby Lake processors when the IGD device is disabled. This should provide to run FSP 2.0-based coreboot on these CPUs families without integrated graphics card. The following boards were used for testing: - Asrock H110M-DVS board (desktop i5-6600) & NVIDIA GTX 1060 as external GPU. Virtualization and GFX 3D acceleration with nouveau driver still works well (tested on VirtualBox 5.1.38 with Ubuntu 18.04.1 as guest and host OS) - Intel KBL-R U RVP board (mobile i5-8350u) without GFX. Payload: tianocore edk2-stable201811-216-g51be9d0.
