ALSA: hda/cirrus: Fix broken audio on hardware with two CS42L42 codecs.
Recently in v6.3-rc1 there was a change affecting behaviour of hrtimers
(commit 0c52310f260014d95c1310364379772cb74cf82d) and causing
few issues on platforms with two CS42L42 codecs. Canonical/Dell
has reported an issue with Vostro-3910.
We need to increase this value by 15ms.

Fixes: 9fb9fa18fb50 ("ALSA: hda/cirrus: Add extra 10 ms delay to allow PLL settle and lock.")
