docs/85100: NOTES: ICH audio device support statement is ambiguous

[Jeroen Ruigrok van der Werven]

Hi Joel,

This PR needs to be updated to reflect that NOTES in CURRENT contains
references to snd_hda and snd_ich.
Also, both manual pages exist. Perhaps a Xref to snd_hda(4) from snd_ich(4) is
needed due to the fact the chipset is typically known as ICH and people will
use that as their first vector of approach.

Nonetheless, it still means that on STABLE the NOTES and snd_ich(4)
documentation needs changes to reflect STABLE does NOT support HDA yet.
