ALSA: hda: Add pplcllpl/u members to hdac_ext_stream 

JIRA: https://issues.redhat.com/browse/RHEL-27515

commit f9eeb6bb13fb5d7af1ea5b74a10b1f8ead962540

    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.
