New Vendor PHY device ID: Ricoh Controller

Hi Takashi, hi other maintainers if any,

I wanted to report another PHY device IDs. But commands failed with timeout. Willing to build and test in case of changes.

Its Ricoh controller integrated with OHCI controller on one chip:
FireWire (IEEE 1394): Ricoh Co Ltd R5C832 PCIe IEEE 1394 Controller (rev 04) [1180:e832]

Target having it is Lenovo Thinkpad T420. And other models as well.

# lsfirewirephy
timeout

$ lsfirewire -v
device fw0:
  vendor ID: 0x001f11
  model ID: 0x023901
  vendor: Linux Firewire
  model: Juju
  guid: 0x0021cc20060f508e

So its submitted to:
<https://ieee1394.docs.kernel.org/en/latest/phy.html#phy-device-ids>

Cheers
