ALSA: hda: Add pplcllpl/u members to hdac_ext_stream
The pplcllpl/u can be used to save the Link Connection Linear Link
Position register value to be used for compensation of the LLP register
value in case the counter is not reset (after pause/resume or
stop/start without closing the stream).
The LLP can be used along with PPHCLDP to calculate delay caused by the DSP
processing for HDA links.
