This adds initial support for soundwire device on sm8250.

Tested with the "wsa" sdw device, which is simpler than the others.

v2 addresses some feedback, but I kept this series as simple as possible.
In particular, I didn't implement CMD_NACKED from FIFO_STATUS, because
the downstream driver doesn't define this bit, so I can't implement it.
Soundwire works without it and It shouldn't be difficult to implement later.

  soundwire: qcom: fix abh/ahb typo
  soundwire: qcom: avoid dependency on CONFIG_SLIMBUS
  soundwire: qcom: add support for mmio soundwire master devices
  soundwire: qcom: add v1.5.1 compatible

Hi Jonathan,
I have tested these patches on RB5 with WSA8810 and they work fine.

I can try to add support to command ignored in future, but for now these 
look good to me!
