[PATCH] emu10k1: add per-voice PTR register dump to /proc entry

[Lee Revell <rlrevell@joe-job.com>]

Summary: This patch adds a register dump for each voice to the /proc
entry.  This functionality will be key for improving the voice allocator
for multichannel support.  Currently these all go in the main file; I
can split these into a file per voice if desired.

Sample output for an idle (15) and running (16) voice:
