Since we handle FIFOs and endpoint separately, using variable named 'ep'
in context of FIFO is misleading, hence we rename it to 'fifo'.

As kill_all_requests() potentially flushes TX FIFO, we should should
free FIFO after calling it. Otherwise FIFO could stay unflushed properly.

Since FIFO is always freed in dwc2_hsotg_ep_disable(), ep->fifo_index
is always 0 in dwc2_hsotg_ep_enable(), hence code inside if() block is
never executed.

Introduce function returning endpoint of given index in active altsetting

to obtain endpoints of currently selected altsetting.

Generate descriptors in new format and attach them to USB function in
prep_descs(). Implement prep_vendor_descs() to supply class specific
descriptors. Change set_alt() implementation and implement clear_alt()
operation. Remove boilerplate code.

As we don't need distinction between interface descriptors for different
speeds, we can remove some amount of unnecessary code. Additionally we
simplify configfs interface of UVC function.

As we have automatic endpoint state handling it's no longer needed.
