Few drivers have own definitions for this constant, so move it to the PCI core. In addition there are several places where the following code sequence is used:

1. Read PCI_STATUS
2. Mask out non-error bits
3. Action based on set error bits
4. Write back set error bits to clear them

As this is a repeated pattern, add a helper to the PCI core.

Most affected drivers are network drivers. But as it's about core PCI functionality, I suppose the series should go through the PCI tree.

Makes good sense to me, thanks for doing this.

v2:

• fix formal issue with cover letter

v3:

• fix dumb typo in patch 7
