snd-hdspm: add PCI ID 1d18:3fc6 for RME HDSPe AIO firmware 200

Hello,

I have an original RME HDSPe AIO PCI express audio card (not an AIO Pro).
RME's current Windows driver identifies it as:

     AIO, Revision=200

After the RME DriverKit firmware update, the card enumerates as:

     08:00.0 Multimedia audio controller [0401]: RME Device [1d18:3fc6] 
(rev d4)

The current snd-hdspm module only advertises the older alias:

     pci:v000010EEd00003FC6sv*sd*bc*sc*i*

Consequently, no driver binds automatically.

The PCI revision is d4, which matches HDSPM_AIO_REV (212/0xd4) in 
sound/pci/rme9652/hdspm.c.

I tested the stock snd-hdspm driver by adding the ID dynamically, with:

     modprobe snd_hdspm
     echo '1d18 3fc6' > /sys/bus/pci/drivers/snd_hdspm/new_id

Result: The card is working 100% correctly for single-speed clocks 
(sample rates 44.1KHz and 48KHz).


Could PCI ID 1d18:3fc6 please be added to snd-hdspm for original HDSPe 
AIO cards using RME's DriverKit-generation firmware?

Please let me know if additional tests or diagnostics are required.

Thanks.

Regards,
