hal: kona: Fix playback for 32bit float file.

32-bit float audio file was unable to get played as float to fixed conversion
was not happening. Add support so that conversion from float to fix happens.

Additionally the hdmi caps are now read as "adev_set_parameters" api is called with
respective controller/stream values.
