ALSA: Constify ratden/ratnum constraints
The ALSA core does not modify the constraints provided by a driver. Most constraint helper functions already take a const pointer to the constraint description, the exception at the moment being the ratden and ratnum constraints. Make those const as well, this allows a driver to declare them as const. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
