ASoC: sirf: Fix potential NULL pointer dereference
There is a potential execution path in which function
platform_get_resource() returns NULL. If this happens,
we will end up having a NULL pointer dereference.

Fix this by replacing devm_ioremap with devm_ioremap_resource,
which has the NULL check and the memory region request.

This code was detected with the help of Coccinelle.

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.
