usb: gadget: add 'quirk_altset_not_supp' to usb_gadget
Due to some UDC controllers may not support altsettings, usb gadget layer
needs to provide a generic way to inform gadget functions about non-standard
hardware limitations.
This patch adds 'quirk_altset_not_supp' field to struct usb_gadget and helper
function gadget_is_altset_supported(). It also sets 'quirk_altset_not_supp'
to 1 in pxa25x_udc and pxa27x_udc drivers, which have such limitation.
