x86: ivybridge: Convert enable_usb_bar() to use DM PCI API
Convert this function over to use the driver model PCI API. In this case we want to avoid using the real PCI devices since they have not yet been probed. Instead, write directly to their PCI configuration address. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
