Now that we have a helper to gather periodic

every driver is using it, we can safely make sure
that usb_endpoint_maxp() returns only bits 10:0 of
wMaxPacketSize which is where the actual packet size
lies.

There might be situations where a Start Transfer
command might fail, if that ever happens, instead of
simply removing the request from our list, we should
give the request back to the gadget driver,
otherwise we might eventually starve it from requests.

No Response Update Transfer is a special type of
Update Transfer command which can be used whenever
we're not relying on XferNotReady to prepare
transfers. With this, we don't need to wait for
CMDACT to be cleared and issue further commands to
the endpoint straight away.

Let's start using this version to skip the long-ish
wait.

The cmd argument we pass to
dwc3_send_gadget_ep_cmd() could contain extra
arguments embedded. When checking for StartTransfer
command, we need to make sure to match only lower 4
bits which contain the actual command and ignore the
rest.
