usb: gadget: f_uac1: disable IN/OUT ep if unused

Browse source

User can configure f_uac1 function via p_chmask/c_chmask
whether uac1 shall support playback and/or capture,
but it has only effect on the created ALSA device,
but not on the USB descriptor.

This patch adds playback/capture descriptors
dependent on that parameter. It is similar to
the same conversion done earlier for f_uac2
