25befdf32a soundwire: generic_bandwidth_allocation: count the bandwidth of active streams only 
sdw_compute_group_params() should only count payload bandwidth of the
active streams which is in the ENABLED and DISABLED state in the bus.
And add the payload bandwidth of the stream that calls
sdw_compute_group_params() in sdw_prepare_stream().

366fd59fb8 soundwire: generic_bandwidth_allocation: add lane in sdw_group_params 
All active streams with the same parameters are grouped together and the
params are stored in the sdw_group struct. We compute the required
bandwidth for each group. However, each lane has individual bandwidth.
Therefore, we should separate different lanes in different params groups.
Add lane variable to separate params groups.

4a7927d54d soundwire: generic_bandwidth_allocation: check required freq accurately 
Currently, we check curr_dr_freq roughly by "if (curr_dr_freq <=
bus->params.bandwidth)" in sdw_compute_bus_params() and check it
accurately in sdw_select_row_col(). It works if we only support one
freq. But, we need to check it accurately in sdw_select_row_col() to
give it a chance to use a higher freq or use multi-lane.

8f4e3343ed Soundwire: add sdw_slave_get_scale_index helper 
Currently, we only set peripheral frequency when the peripheral is
initialized. However, curr_dr_freq may change to get required bandwidth.
For example, curr_dr_freq may increase from 4.8MHz to 9.6MHz when the
4th stream is opened. Add a helper to get the scale index so that we can
get the scale index and program it.

fdd1faeeec soundwire: generic_bandwidth_allocation: skip DEPREPARED streams 
We should not blindly walk through all the m_rt list, since it will
have the side effect of accounting for deprepared streams.

This behavior is the result of the split implementation where the
dailink hw_free() handles the stream state change and the bit
allocation, and the dai hw_free() modifies the m_rt list. The bit
allocation ends-up using m_rt entries in zombie state, no longer
relevant but still used.

f1b3dba690 soundwire: stream: set DEPREPARED state earlier 
The existing logic is problematic in that we deprepare all the ports,
but still take into account the stream for bit allocation by just
walking through the bus->m_rt list.

This patch sets the state earlier, so that such DEPREPARED streams can
be skipped in the bandwidth allocation (to be implemented in a
follow-up patch).

if the SoundWire device uses devres this can run before the actual device
clean up, potentially clearing the mapping whilst it is still in use.

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.
