Takashi Iwai 37b3e56d89 ALSA: usb-audio: More refactoring of hw constraint rules
Although we applied a workaround for the hw constraints code with the
implicit feedback sync, it still has a potential problem.  Namely, as
the code treats only the first matching (sync) endpoint, it might be
too restrictive when multiple endpoints are listed in the substream's
format list.

This patch is another attempt to improve the hw constraint handling
for the implicit feedback sync.  The code is rewritten and the sync EP
handling for the rate and the format is put inside the fmt_list loop
in each hw_rule_*() function instead of the additional rules.  The
rules for the period size and periods are extended to loop over the
fmt_list like others, and they apply the constraints only if needed.
