e70140ba0d Get rid of 'remove_new' relic from platform driver struct
The continual trickle of small conversion patches is grating on me, and
is really not helping.  Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:

  /*
   * .remove_new() is a relic from a prototype conversion of .remove().
   * New drivers are supposed to implement .remove(). Once all drivers are
   * converted to not use .remove_new any more, it will be dropped.
   */

This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.

I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.

Then I just removed the old (sic) .remove_new member function, and this
is the end result.  No more unnecessary conversion noise.

63dc588e7a soundwire: amd: fix for wake interrupt handling for clockstop mode
When SoundWire Wake interrupt is enabled along with SoundWire Wake
enable register, SoundWire wake interrupt will be reported
when SoundWire manager is in D3 state and ACP is in D3 state.

When SoundWire Wake interrupt is reported, it will invoke runtime
resume of the SoundWire manager device.

In case of system level suspend, for ClockStop Mode SoundWire Wake
interrupt should be disabled.
It should be enabled only for runtime suspend scenario.
Change wake interrupt enable/disable sequence for ClockStop Mode in
system level suspend and runtime suspend sceanrio.

6543ac13c6 soundwire: bus: introduce controller_id
The existing SoundWire support misses a clear Controller/Manager
hiearchical definition to deal with all variants across SOC vendors.

a) Intel platforms have one controller with 4 or more Managers.
b) AMD platforms have two controllers with one Manager each, but due
to BIOS issues use two different link_id values within the scope of a
single controller.
c) QCOM platforms have one or more controller with one Manager each.

This patch adds a 'controller_id' which can be set by higher
levels. If assigned to -1, the controller_id will be set to the
system-unique IDA-assigned bus->id.

The main change is that the bus->id is no longer used for any device
name, which makes the definition completely predictable and not
dependent on any enumeration order. The bus->id is only used to insert
the Managers in the stream rt context.

1ec33e22b8 soundwire: amd: Improve error message in remove callback
Returning an error code in the remove callback yields to an error
message

	remove callback returned a non-zero value. This will be ignored.

After that the device is removed anyhow. Improve the error message to at
least say what the actual problem is. While touching that code, convert
the driver to the .remove_new() callback which returns no value with the
same effect as returning zero in a .remove() callback.

As the return value is ignored by the core the only effect of this patch
is to improve the error message. (And the motivating effect is that
there is one less driver using .remove().)
