dm: x86: minnowmax: Move PCI to use driver model
Adjust minnowmax to use driver model for PCI. This requires adding a device tree node to specify the ranges, removing the board-specific PCI code and ensuring that the host bridge is configured. Reviewed-by: Bin Meng <bmeng.cn@gmail.com> Signed-off-by: Simon Glass <sjg@chromium.org>
