Commit 9477c58e ("ALSA: hda - Reorganize controller quriks with bit
flags") changed the driver type compares into various quirk bits.
However, the check for AZX_DCAPS_NO_TCSEL got reverted: instead of
clearing TCSEL for chipsets that have that standard capability, it
cleared then when the NO_TCSEL bit was set.

This can lead to noise and repeated sounds - a weird "echo" behavior.
As the comment just above says: "Ensuring these bits are 0 clears
playback static on some HD Audio codecs".  Which is definitely true at
least on my Core i5 Westmere system.

The software division functions never had unwinding annotations
added. Currently, when a division by zero occurs the backtrace shown
will stop at Ldiv0 or some completely unrelated function. Add
unwinding annotations in hopes of getting a more useful backtrace

Several crashes in cleanup_once() were reported in recent kernels.

Commit d6cc1d64 (inetpeer: various changes) added a race in
unlink_from_unused().

One way to avoid taking unused_peers.lock before doing the list_empty()
test is to catch 0->1 refcnt transitions, using full barrier atomic
operations variants (atomic_cmpxchg() and atomic_inc_return()) instead
of previous atomic_inc() and atomic_add_unless() variants.

We then call unlink_from_unused() only for the owner of the 0->1
transition.

Add a new atomic_add_unless_return() static helper

With help from Arun Sharma.

Adding support for the twl6025. Major difference in the twl6025 is the
group functionality has been removed from the chip so this affects how
regulators are enabled and disabled.

The names of the regulators also changed.

The DCDCs of the 6025 are software controllable as well.

Since V1

Use the features variable passed via platform data instead of calling
global function.

Change the very switch like if statements to be a more readable
switch statement.

Since V2

twl6025 doesn't use remap so remove it from the macros.

Since V3

enable/disable functions for 4030/6030 were seperated upstream so rebase
on top of this. Change DCDC reference to SMPS as this is used in TRM.
Change list_voltage slightly to have less code.
