When test uvc hotplug, it may caused a dead lock in the
following case:
1. Test on Rockchip platforms used USB DWC2 controller.
2. Set USB as UVC gadget and connect to PC.
3. Open UVC to preview picture, and then disconnect USB.
Then a dead lock happens.
1. usb_function_deactivate() hold the cdev->lock;
2. usb_function_deactivate() --> usb_gadget_deactivate()
--> usb_gadget_disconnect() --> dwc2_hsotg_disconnect()
--> composite_disconnect() try to get the cdev->lock again.
According to the comment for cdev->lock, it's used to protect
deactivations and delayed_status count, so we can drop the
spinlock safely before do usb_gadget_deactivate(), and hold
the spinlock again after usb_gadget_deactivate() done to
protect the deactivations.

According to the spec "USB Interface Association Descriptor Device
Class Code and Use Model"[1], the Interface Association Descriptor
(IAD) is needed for composite device which has multiple interfaces
controlled independently of each other. Without the IAD, the device
may not work as expected because the USB system software will not
properly bind the interfaces with drivers (e.g UAC1 && UVC composite
device not recognized in Win10).

We need to dynamically resize the TxFIFOs for some cases
where the default values don't match.
Test on RK1808-stick board, configurate the usb with four
functions "rndis, ntb, mass_storage, acm", the default
values of TxFIFOs is:
GTXFIFOSIZ(0) = 0x00000042
GTXFIFOSIZ(1) = 0x00420184
GTXFIFOSIZ(2) = 0x01c60184
GTXFIFOSIZ(3) = 0x034a0184
GTXFIFOSIZ(4) = 0x04ce0184
GTXFIFOSIZ(5) = 0x06520184
GTXFIFOSIZ(6) = 0x07d6002a
The ep6-in is used for acm ep-in which maxpacket is 1024B,
but the default fifo size of ep6-in is only 336B, less than
the length of the ep maxpacket, it cause acm works abnormally.
This patch creates a simple function to allocate enough TxFIFO
space for each of the enabled endpoints.

This patch adds bulk endpoint for uvc to be used as
video streaming transfer. By default, the uvc gadget
still uses isoc endpoint for video streaming.
The important difference between the bulk and isoc
method is that, alt-settings in a video streaming
interface are supported only for isoc endpoints as
there are different alt-settings for zero-bandwidth
and full-bandwidth use-cases, but the same is not
true for bulk endpoints, as they support only a single
alt-setting.
How to use:
1. Enable the bulk transfer:
echo 1 > /config/usb-gadget/g1/functions/uvc.name/streaming_bulk
2. Disable the bulk transfer:
echo 0 > /config/usb-gadget/g1/functions/uvc.name/streaming_bulk
3. Testing the uvc bulk function transfer:
device: run the uvc-gadget program
# uvc-gadget -b -u /dev/video<uvc video node #> -v /dev/video<vivid video node #>

We find that the UAC2 gadget can't be recognized on Windows 10.
It's because that the descriptors of UAC2 doesn't meet the
requirements of Windows.
According to the USB Audio 2.0 Drivers of Windows [1], if the
bmAttributes of OUT-EP in the audio stream interface is set
to asynchronous (use USB_ENDPOINT_SYNC_ASYNC), then a feedback
endpoint must be implemented in the respective alternate setting
of the AS interface. The Windows driver does not support implicit
feedback.
However, it's difficult to implement the feedback endpoint now.
So the patch changes the bmAttributes of OUT-EP to adaptive, and
changes the bmAttributes of IN-EP to synchronous at the same time.
This patch also sets the wTerminalType of terminal descriptor to
microphone and speaker by default.
With this patch, we also fix the wTotalLength of the ac_hdr_desc.

The Seagate Expansion Portable Drive HDD (idVendor=0bc2, idProduct=2321) is reported to fail to work on rockchip platforms
with the following error message when do read/write operation by dd command:
xhci-hcd xhci-hcd.11.auto: Ring expansion failed
According to tkaiser's suggestion[1], we can try to increase the kernel's
coherent-pool memory size to fix this issue. The kernel coherent-pool memory
size was limited at 256KB by default. When set the DEFAULT_DMA_COHERENT_POOL_SIZE
to 1MB, the error "Ring expansion failed" can be fixed, but it still not
work with the other error message:
xhci-hcd xhci-hcd.12.auto: ERROR Unknown event condition 34 for slot 1 ep 3 , HC probably busted

When the combphy work as USB3 PHY (e.g. RK1808 EVB USB3 port),
the PHY init and exit ops are called dynamically in the runtime
process of USB3 controller driver.
Because it only needs to init the USB3 PHY once in the PHY init,
and reinit the USB3 PHY in the runtime process may cause USB3 work
abnormally, so this patch doesn't clear the phy_initialized flag
for USB3 in the PHY exit ops.
