[PATCH 0/2] PCI: dwc: Fix MEM outbound iATU setup

[Xincheng Ji]

This series follows up on the recently applied MEM outbound iATU support.

The DesignWare outbound no-match path does not translate addresses. Skip
MEM outbound iATU programming whenever atu.parent_bus_addr matches
atu.pci_addr, rather than relying on a driver-specific flag. CFG and I/O
accesses, as well as non-identity-mapped MEM ranges, continue to use
outbound iATU windows.

Patch 1 removes bypass_ob_mem_iatu from the generic DesignWare PCIe host
code and directly compares the parent-bus and PCI addresses before
programming a MEM outbound iATU window.

Patch 2 removes the now-redundant bypass_ob_mem_iatu assignment from the
UltraRISC DP1000 driver.
