1. use the same mutex to serialize the calls from user application.
2. keep iommu attached state when last video is closed,
because the user application may still access the buffer allocated
by v4l2 driver.

64bit SoCs with 32bit code need some different configs, eg. textofs...
So we need a independent defconfig.

This patch tuning lane 0 TX driver swing for USB 3.0 to
get larger swing for LFPS.
Test on RK1808-stick board:
offset[0x21b8] 5G LFPS Peak-Peak Differential Output Voltage
0xd9 Actual Value: 807.9mv Margin: 2.0%
0xe9 Actual Value: 832.2mv Margin: 8.1%
0xf9 Actual Value: 842.7mv Margin: 10.7%
We set PHY register offset[0x21b8] to 0xe9 in this patch.

When the clients are 32 bits while the kernel is 64 bits,
we need to translate the memory address before accessing.
The previous commit was refreshed by ddk update.

Disable this api by default.

When handing the SETUP packet by composite_setup(), we will release the
dwc->lock. If we get the 'USB_GADGET_DELAYED_STATUS' result from setup
function, which means we need to delay handling the STATUS phase.
But during the lock release period, maybe the request for handling delay
STATUS phase has been queued into list before we set 'dwc->delayed_status'
flag or entering 'EP0_STATUS_PHASE' phase, then we will miss the chance
to handle the STATUS phase. Thus we should check if the request for delay
STATUS phase has been enqueued when entering 'EP0_STATUS_PHASE' phase in
dwc3_ep0_xfernotready(), if so, we should handle it.

Currently the link_state is uninitialized and the default value is 0(U0)
before the first time we start the udc, and after we start the udc then
stop the udc, the link_state will be undefined.
We may have the following warnings if we start the udc again with
an undefined link_state:
