[alsa-devel] [PATCH] ASoC: Intel: Fix build with CONFIG_SLEEP enabled.

[Liam Girdwood]

Fix the following build error when CONFIG_SLEEP is enabled and CONFIG_RUNTIME
is disabled. The BDW ADSP sleep PM functionality depends on the runtime pm
calls for context save/restore.

All error/warnings:

>> ERROR: "snd_soc_suspend" undefined!
>> ERROR: "snd_soc_resume" undefined!
