Eliminate the uninitialized 'nval' in cs35l56_hda_read_acpi() if a
system-specific quirk overrides processing of the dev-index property.
The value is now stored in a new 'num_amps' member of struct cs35l56_hda
so that the quirk handler can set the value.
The quirk for the Lenovo Yoga Book 9i GenX replaces the values from the
dev-index property with hardcoded indexes. So cs35l56_hda_read_acpi() would
then skip reading the property. But this left the 'nval' local variable
uninitialized when it is later passed to cirrus_scodec_get_speaker_id().
