[0/3] PCI endpoint additional pci_epc_set_bar() checks

Hello all,

This series adds some extra checks to ensure that can not program the iATU
with an address that we did not intend to use.

These checks would have given resulting in an error when testing some of
the earlier revisions of Frank's doorbell patches (which did not handle
fixed BARs properly).

With these checks in place, we will hopefully avoid unnecessary debugging
in the future.


Kind regards,
Niklas
