PCI: Add quirk for setting valid class for TI816X Endpoint

commit 63c4408074cbcc070ac17fc10e524800eb9bd0b0 upstream.

TI816X (common name for DM816x/C6A816x/AM389x family) devices configured
to boot as PCIe Endpoint have class code = 0. This makes kernel PCI bus
code to skip allocating BARs to these devices resulting into following
type of error when trying to enable them:

"Device 0000:01:00.0 not available because of resource collisions"

The device cannot be operated because of the above issue.

This patch adds a ID specific (TI VENDOR ID and 816X DEVICE ID based)
'early' fixup quirk to replace class code with
PCI_CLASS_MULTIMEDIA_VIDEO as class.
