ASoC: Intel: avs: Ignore codecs with no suppoting driver

HDMI codecs which are present and functional from audio perspective lack
i915 support on drm side what results in -ENODEV during the probing
sequence. There is no reason to perform recovery procedure e.g.: reset

ASoC: Intel: avs: Preallocate memory for module configuration

In order to instantiate modules on the firmware side, the driver sends
payload with module configuration. In some case size of this information
is not known before hand, so driver allocates temporary memory during

preallocating maximum buffer. This removes the time spend on allocating
