Remove the workarounds added in commit fa763f1b2858 ("ALSA: hda - Force polling mode on CNL for fixing codec communication") and commit a8d7bde23e71 ("ALSA: hda - Force polling mode on CFL for fixing codec communication").
The workarounds are no longer needed after the more generic change done in commit 2756d9143aa5 ("ALSA: hda - Fix intermittent CORB/RIRB stall on Intel chips"). This change applies to a larger set of hardware and covers CFL and CNL as well.
Similar change was already done to SOF DSP HDA driver with no regressions detected.
