ALSA: hda: cs35l41: Force a software reset after hardware reset

Browse source

To ensure the chip has correctly reset during probe and system suspend,
we need to force a software reset, in case of systems where the
hardware reset is not available.

The software reset register was labelled as volatile but not readable,
however, it is readable, (just returns 0x0). Adding it to readable
registers means it will be correctly treated as volatile, and thus
will not be cached.
