Upadate lpass cpu and platform driver to support audio over dp.
Also add lpass-hdmi.c and lpass-hdmi.h.

Before going into detail review, I see real issue in the overall
approach here to add new interface to exiting lpass!!
Intention of struct lpass_variant is to address differences between
SoCs or different lpass versions. But you should not duplicate this
and use it for addressing differences between each lpass interfaces!
All the dai related register offsets should still go in to this
structure and driver should be able to know which dai its talking to
based on snd_soc_dai_driver id and select correct register offset.
Do You suggest to use separate structure like struct
lpass_hdmi_interface in lpass_data?
Also on the other note, can you please split the patch if possible so
that it will be easy for review. Specially I would like to see header
file changes specific to adding new interface to be separate then
followed by the actual interface implementation and then the user.
Okay, will split the patch.
I also see some unrelated changes like changing buffer sizes, which
should go into different patch!
Okay we will separate the patch.
