Add support for BT Soundwire port configurations.
Add support for flow control modes for fractional channel rates.
Configure slave side data ports for flow controls modes.
Fix the direction adn offset1 fields for Tx ports on BT Soundwire.
When the flow control mode is not required,
update the slave configuration accordingly.
Sample Interval HIGH field in slave port controls needs to be
reset to zero when Sample Interval value is less than 255.
Avoid clock stop mode for bt swr slave during runtime suspend call.
In case of fractional sampling rates, additional offset bits need
to be added between samples to carry flow control information.

During PDR, WSA auto-enumeration is swapped (WSA2
gets enumerated before WSA1 unlike bootup).
This causes offset1s to be swapped because dev_nums are
swapped and are used to index into device tree data.
Store dev_id during enumeration and use this instead of
dev_num to pick out offset1 from device tree data.

When headset is inserted and reboot device sometimes
headset is not detected after reboot as host_irq from
swr slave gets masked. This is because of cmd error seen
after clearing all irq which results in fifo flush.
Read swrslave irq before clearing so as to resolve cmd error.
Also enable host irq after clearing enum interrupt at master.
This ensures irq is properly enabled.

commands in fifo and comparing with fifo depth before
every read/write. If no. of commands is equal to fifo
depth then give some delay and retry. If no of outstanding
commands are still equal to fifo depth then flush fifo
and try writing/reading from fifo again.

Headset insertion/removal is not detected sometime due to
fifo read failure due to swr underflow. This is because if
headset sva is enabled, during clk switch swr force stop
happens and if mbhc has already taken pm vote for 3sec
further mbhc reads/writes will fail. If swr is in clk switch
mode then call swrm runtime_resume during reads/writes
to resolve issue.
