ALSA: hda: cs35l41: Check runtime suspend capability at runtime_idle 

The runtime PM core checks with runtime_idle callback whether it can
goes to the runtime suspend or not, and we can put the boost type
check there instead of runtime_suspend and _resume calls.  This will
reduce the unnecessary runtime_suspend() calls.

Fixes: 1873ebd30c ("ALSA: hda: cs35l41: Support Hibernation during Suspend")
