Adjust these files to use the driver-model PCI API instead of the legacy functions.
Signed-off-by: Simon Glass sjg@chromium.org ---
Changes in v2: - Rename pci_run_vga_bios() to dm_pci_run_vga_bios() - Require driver model with pci_rom.c - Use dev_get_parent_platdata() instead of re-reading values from the device
