dm: x86: ivybridge: Convert graphics init to use DM PCI API
Use the driver-model PCI functions here where possible. For now we have to search for the device with pci_bus_find_bdf() but at some point we can put this in a proper driver and avoid this. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
