PCI: Add quirk to disable MSI-X support for Amazon's Annapurna Labs Root Port

The Root Port (identified by [1c36:0031]) doesn't support MSI-X. On some
platforms it is configured to not advertise the capability at all, while
on others it (mistakenly) does. This causes a panic during
initialization by the pcieport driver, since it tries to configure the
MSI-X capability. Specifically, when trying to access the MSI-X table
a "non-existing addr" exception occurs.

Example stacktrace snippet:

Notice that this quirk also disables MSI (which may work, but hasn't
been tested nor has a current use case), since currently there is no
standard way to disable only MSI-X.
