Use the new device-level suspend/resume hooks for Gadget Zero; always enable them with the OTG test mode; and support remote wakeup on both configurations even in non-OTG mode. This ensures that both configurations can pass the USBCV remote wakeup tests when the OTG test mode is enabled. This changes behavior by adding autoresume support to the loopback config even in non-OTG mode; the test failure was that it didn't work in OTG mode.

Address one open question in the composite gadget framework: Yes, we should have device-level suspend/resume callbacks in addition to the function-level ones.

Roel Kluin pointed out that transfer_buffer_lengths in struct urb was declared as an 'int'. This patch changes this field to be 'u32' to prevent any potential negative conversion and comparison errors. This triggered a few compiler warning messages when these fields were being used with the min macro, so they have also been fixed up in this patch.

Add the vbus_draw() callback to inform the transceiver, if it exists, how much current may be drawn. The decision is taken on gadget driver side using the configuration chosen by the host and its bMaxPower field. Some systems can use the host's VBUS supply to augment or recharge a battery. (There's also a default of 100 mA for unconfigured devices, or 8 mA if they're OTG devices.)

Restore some code that was wrongly dropped from the RNDIS driver, and caused interop problems observed with OpenMoko. The issue is with hardware which needs help conforming to part of the USB 2.0 spec (section 8.5.3.2); some can automagically send a ZLP in response to an unexpected IN, but not all chips will do that. We don't need to check the packet length ourselves the way earlier code did, since the UDC must already check it. But we do need to tell the UDC when it must force a short packet termination of the data stage. (Based on a patch from Aric D.

While disabling an endpoint the driver nuking any pending requests, thus completing them with -ESHUTDOWN status. But the driver doesn't clear the tx_req, which means that a next TX request (after ep_enable), might get stalled, since the driver won't queue the new reqests. This patch fixes a bug I'm observing with ethernet gadget while playing with ifconfig usb0 up/down (the up/down sequence disables and enables `in' and `out' endpoints).

Before freeing an endpoint's muram memory, we should stop all activity of the endpoint, otherwise the QE UDC controller might do nasty things with the muram memory that isn't belong to that endpoint anymore.

Freescale QE UDC controllers can't report the "port change" states, so the only way to handle disconnects is to process bus reset interrupts. The bus reset can take some time, that is, few irqs. Gadgets may print the disconnection events, and this causes few repetitive messages in the kernel log. This patch fixes the issue by using the usb_state machine, if the usb controller has been already reset, just quit the reset irq early.
