usb: ci_udc: fix request allocation when endpoints are disabled
The ci_udc driver request allocation assumes that the endpoint descriptor
pointer is set to retrieve the endpoint number, but that is only true
when the endpoint is enabled. This results in a NULL ptr dereference
which for me happens to return 0 value. This causes the EP0 request
struct to be returned for other endpoints. Some gadget drivers like
fastboot and USB MS work fine, but ethernet does not.
Really, the ci_udc driver is the oddball here doing this EP0 special
case handling Stephen added. All the other drivers alloc/free functions
are pretty much the same with the only variation being the size of the
private struct. This could all be consolidated to a common function.

usb: gadget: fastboot: Dequeue the previous IN request for the current request
Recent versions of the fastboot tool will query the partition type before doing
an operation on a partition (such as erase, flash, etc). It will then submit
the operation as soon as the response for the partition type is received.
Usually, the MUSB controller will see that the partition type request return
status was read by the host at the very same time as the actual operation
request is submitted by the host. However, the operation will be read first
(int_rx is handled first in musb_interrupt) and after it is completed, the
fastboot USB gadget driver will send another return status. Hence, this happens
before the musb gadget framework has had a chance to handle the previous
acknowledgement that the host read the return status and dequeue the request.
The host will then usually empty the FIFO by the time musb_interrupt gets around
handling the return status acknowledgement (for the previous request, this is
still on the same musb_interrupt call), so no other interrupt is generated and
the most recent return status acknowledgement remains unaccounted for.
It will then be used as a response for the next command, and the proper response
for it will be delayed to the next command, and so on.
Dequeuing the previous IN request in the fastboot code ensures that no previous
return status remains. It is acceptable to do it since there is no callback to
it anyways.

dm: eth: Avoid blocking on packet reception
Some devices can take a long time to work out whether they have a new packet
or now. For example the ASIX USB Ethernet dongle can take 5 seconds to do
this, since it waits until it gets a new packet on the wire before allowing
the USB bulk read packet to be submitted.
At present with driver mode the Ethernet receive code reads 32 packets. This
can take a very long time if we must wait for all 32 packets. The old code
(before driver model) worked by reading a single set of packets from the USB
device, then processing all the packets with in. It would be nice to use
the same behaviour with driver model.
Add a flag to the receive method which indicates that the driver should try
to find a packet if available, by consulting the hardware. When the flag is
not set, it should just return any packet data it has already received. If
there is none, it should return -EAGAIN so that the loop will terminate.

first child being non-active as in this example also causes usb_get_dev_index
