For setting the pin-control values more safely to match with the
actual pin capability bits, a copule of new helper functions,
snd_hda_set_pin_ctl() and snd_hda_set_pin_ctl_cache(), are
introduced.  These are simple replacement of the codec verb write with
AC_VERB_SET_PIN_WIDGET but do more sanity checks and filter out
superfluous pin-control bits if they don't fit with the corresponding
pin capabilities.

Some codecs are screwed up or ignore the command when such a wrong bit
is set.  These helpers will avoid such secret errors.

In patch_ca0132.c, the error returned from chipio_write() isn't checked
always.  Also, the power-up/down sequence isn't tracked properly in some
error paths.

Lots of sound drivers were getting module.h via the implicit presence
of it in <linux/device.h> but we are going to clean that up.  So
fix up those users now.
