Hi. This clean up looks good basically.
But when conventional pci device is accessed via MMCONFIG area,
addr &= addr_mask doesn't work as expected.
The config area of [256, 4K) of conventional pci should have no effect.

Introduce pci_config_read/write helpers to split up config space
accesses that are not length-aligned. This particularly avoids that each
and every device needs to check for config space overruns. Also move the
access length assertion to the new helpers.
