QUIRK_FLAG_SKIP_IFACE_SETUP was introduced into usb-audio before without
appropriate documentation, so add it.
Fixes: 38c322068a26 ("ALSA: usb-audio: Add QUIRK_FLAG_SKIP_IFACE_SETUP")

Similar to bit 24 but for capture streams
+ * bit 26: ``skip_iface_setup``
+ Skip the probe-time interface setup (usb_set_interface,
+ init_pitch, init_sample_rate); redundant with
+ snd_usb_endpoint_prepare() at stream-open time
This module supports multiple devices, autoprobe and hotplugging.
