Gen 1 and 2 chips use the same ID for NHI, bridges and switch.
Gen 3 chips and onward use a distinct ID for the NHI.
No functional change intended.

Light Ridge (CV82524) was the very first copper Thunderbolt controller,
introduced 2010 alongside its fiber-optic cousin Light Peak (CVL2510).
Consequently the chip suffers from some teething troubles:
MSI is broken for hotplug signaling on the downstream bridges: The chip
just never sends an interrupt. It requests 32 MSIs for each of its six
bridges and the pcieport driver only allocates one per bridge. However
I've verified that even if 32 MSIs are allocated there's no interrupt
on hotplug. The only option is thus to disable MSI, which is also what
OS X does. Apparently all Thunderbolt chips up to revision 1 of Cactus
Ridge 4C are plagued by this issue so quirk those as well.
The chip supports a maximum hop_count of 32, unlike its successors
which support only 12. Fixup ring_interrupt_active() to cope with
values >= 32.
Another peculiarity is that the chip supports a maximum of 13 ports
whereas its successors support 12. However the additional port (#5)
seems to be unusable as reading its TB_CFG_PORT config space results
in TB_CFG_ERROR_INVALID_CONFIG_SPACE. Add a quirk to mark the port
disabled on the root switch, assuming that's necessary on all Macs
using this chip.
