clang-format: re-format for clang-18

clang-format-18 isn't compatible with the clang-format-17 output, so we
need to reformat the code with the latest version. The way clang-18
handles lambda formatting also changed, so we have made changes to the
organization default style format to better handle lambda formatting.

See I5e08687e696dd240402a2780158664b7113def0e for updated style.
See Iea0776aaa7edd483fa395e23de25ebf5a6288f71 for clang-18 enablement.

Add support for specifying UDC that HID gadget will connect to

Currently, HID gadget always connects to the USB virtual hub port
under /sys/bus/platform/devices/1e6a0000.usb-vhub, which only works
on ASPEED platform.

This commit adds support for specifying UDC that HID gadget will
connect to, it could be useful for non-ASPEED platform. Although there
are still some other ASPEED-specific behaviors need to be addressed,
but this commit is the first step for non-ASPEED platform.

Tested:
Specify UDC by '-u' parameter and HID gadget will connect to it. Otherwise,
HID gadget will connect to the USB virtual hub port.

Implement optional per-frame CRC calculation to save bandwidth

Current implementation is very CPU-efficient as it's not processing
JPEG-encoded data received from V4L2 at all.

This patch implements an optional mode where for each frame that's about
to be sent a CRC32 is calculated and if this client has already received
it before, the transmission is skipped. This of course adds some
noticeable CPU load (proportional to the frame rate requested and the
encoded JPEG size); on AST2500 it's taking about 10 % CPU when showing a
relatively complex GUI login screen with 15 FPS.

Reducing required bandwidth to 0 for static images helps a lot when
using IP KVM via poor connections, e.g. provided by cellular network
operators or some hotels, so can be beneficial for certain common
usecases.

The next optimisation to try is to dynamically alter the frame rate,
automatically ramping it up as soon as the changes start happening and
lowering after a period of inactivity; it's not yet clear if V4L2 allows
this.
