x86/PCI: select direct access mode for mmconfig option
Direct access is needed in mmconf mode too. There are two reasons:
1. we need it to access first 256 bytes. We have bug before that
using mmconf to access pci config space hangs system (when
resizing BARs), so we use type1 config for legacy config space.
2. when doing mmconfg bar checking, we need access ACPI _CRS,
which might access PCI config space.
