ALSA: hda: acpi: Make driver's match data const static

The driver's match data, nvidia_hda_data, is referred only locally,
and should be static.  Also, as it's a read-only data, it can be
gracefully const, too.

Fixes: 4b214c9bbe26 ("ALSA: hda - Add new driver for HDA controllers listed via ACPI")
