[PATCH v2] docs: Remove stale ISDN parameters

[PATCH v2] docs: Remove stale ISDN parameters

[Costa Shulyupin]

The icn= and pcbit= parameters referenced drivers removed in
commit 02bbd9802da7 ("staging: i4l: delete the whole thing").

Remove the stale parameter entries and the now-unused ISDN tag
from the legend.

Hi,
Your Signed-off-by: should be immediately after the
Assisted-by: line and before the first "---" line.

I'm curious: how and why did Claude assist you in this?

Anyway:

I've asked Claude to find and fix outdated content in the documentation.

This arrangement caused your signoff to be stripped out on application.
I've put it back, but please follow the normal patch format in the
future.

Thanks,
