[PATCH 3/6] ASoC: Intel: catpt: Fix probing order of driver components

[Cezary Rojewski <cezary.rojewski@intel.com>]

catpt_dai_pcm_new() is called during the bring up sequence of the
machine board device. That device is a child of the ACPI device the
catpt-driver attaches to. The function manipulates pm_runtime_xxx() to
ensure its parent is woken up before sending IPCs. If the parent's
pm_runtime is not configured before that happens, errors will occur.
