- no need to explicitly switch off vga anymore - use pcid for VMs which improves TLB usage if multiple vCPUs on same pCPU is used, which happens to happen on Sculpt. Issue genodelabs#5206

separately. Genode's pc_platform_drv is in now capable of driving the Intel IOMMU completely. The "iommu" option is now split up into "iommu_intel" and "iommu_amd", and is off for Intel with this commit. Fixes genodelabs#5206

The Genode pc_platform_drv component is now able to drive the iommu for Intel. Add an option to enable Intel/AMD iommu handling separately.
