soc/intel/skylake: Skip disabled IGD device

If IGD PCI device is disabled:
1. BAR for the device will be 0.
2. There is no need to allocate framebuffer for this device.

Some early SOCs don't have GFX model fuse by default hence
we need to add a check to ensure PCI device is enable. This
code to avoid die inside coreboot for missing resources.
