33db744abe ASoC: sirf: drop owner assignment from platform_drivers
A platform_driver does not need to set an owner, it will be populated by the
driver core.

9779caf9fa ASoC: sirf-usp: Fixed a bug for playback and capture work at the same time
1. The startup function invoked when the playback and capture.
   If start playback when capturing, the registers are re-initinitialised.
   That cause the playback fail. So move the startup code into runtime resume.
2. Modified: If non RUNTIME_PM support, the probe need enable clock and
   initinitialise registers.
3. Refine code.

90eb1ab9e4 ASoC: sirf: provide pm-runtime functions when needed
The newly introduced sirf-usp driver defines sirf_usp_pcm_{suspend,resume}
functions only when PM_RUNTIME is enabled, but also uses them when that
is disabled and only PM_SLEEP is turned on, resulting in this error:

../sound/soc/sirf/sirf-usp.c: In function 'sirf_usp_pcm_suspend':
../sound/soc/sirf/sirf-usp.c:308:3: error: implicit declaration of function 'sirf_usp_pcm_runtime_suspend' [-Werror=implicit-function-declaration]
   sirf_usp_pcm_runtime_suspend(dev);
   ^
../sound/soc/sirf/sirf-usp.c: In function 'sirf_usp_pcm_resume':
../sound/soc/sirf/sirf-usp.c:319:3: error: implicit declaration of function 'sirf_usp_pcm_runtime_resume' [-Werror=implicit-function-declaration]
   ret = sirf_usp_pcm_runtime_resume(dev);
   ^
cc1: some warnings being treated as errors

To fix that, this patch changes the #ifdef to CONFIG_PM, which
is enabled when at least one of PM_SLEEP or PM_RUNTIME are enabled.

a731e217df ASoC: sirf: Add SiRF audio port driver is used by SiRF internal audio codec
This driver is used by SIRF internal audio codec.
Use dedicated SiRF audio port TXFIFO and RXFIFO
Supports two DMA channels for SiRF audio port TXFIFO and RXFIFO
The audio port like as audio bus such as i2s.
