isx019 driver freezes by I2C access in the interrupt context.
This I2C access is intended to stop data output from FPGA.
Delete this I2C access for the following reasons.
- Data output from FPGA does not affect power consumption
- There are no problems in capture restart without data output stop
since restart is done by image data block first.
1. support doublebuffer swtich for overlay layer
2. Add display area ioctl to scale the active area of the overlay layer
to a specific region on the LCD through hardware.

When the value that is out of range is specified in ioctl(VIDIOC_S_CTRL) and
ioctl(VIDIOC_S_EXT_CTRLS), returned value should be not EINVAL but ERANGE.
video driver does not support flags member of ioctl(VIDIOC_QUERYCTRL)
and ioctl(VIDIOC_QUERY_EXT_CTRL).
But, ioctl returns with the flags member that has the garbage value.
Add initialization of flags member to avoid return of the garbage value.
1. Update all CMakeLists.txt to adapt to new layout
2. Fix cmake build break
3. Update all new file license
4. Fully compatible with current compilation environment(use configure.sh or cmake as you choose)
------------------
How to test
From within nuttx/. Configure:
cmake -B build -DBOARD_CONFIG=sim/nsh -GNinja
cmake -B build -DBOARD_CONFIG=sim:nsh -GNinja
cmake -B build -DBOARD_CONFIG=sabre-6quad/smp -GNinja
cmake -B build -DBOARD_CONFIG=lm3s6965-ek/qemu-flat -GNinja
(or full path in custom board) :
cmake -B build -DBOARD_CONFIG=$PWD/boards/sim/sim/sim/configs/nsh -GNinja
This uses ninja generator (install with sudo apt install ninja-build). To build:
$ cmake --build build
menuconfig:
$ cmake --build build -t menuconfig
--------------------------
2. cmake/build: reformat the cmake style by cmake-format
https://github.com/cheshirekow/cmake_format
$ pip install cmakelang
$ for i in `find -name CMakeLists.txt`;do cmake-format $i -o $i;done
$ for i in `find -name *\.cmake`;do cmake-format $i -o $i;done

When updating the full-screen data, sq_ init() will clear the updqueue and add just one new full-screen data to the updqueue. So when the vnc_updater thread is awakened, it may read a null data due to multiple reading, leading to vnc_updater thread exited , which is not expected.

set touch.maxpoint to 1 in vnc_server.c for circbuf_init，otherwise
touch_event will circbuf_overwrite a wrong value.
test step:vnc run lvgldemo，test input event

Considering that the future fb needs to achieve dynamic resolution, the address and size of fbmem will be redistributed on the bottom driver side, so remove fbmem, fblen, and bpp cached in fb_chardev_s, and change it to call getplaneinfo every time to re-acquire panel info from the bottom driver. Avoid cache coherency problems.

When executing up_fbinitialize, the driver may turn on the vsync interrupt. If the vsync interrupt calls fb_pollnotify before executing fb->vtable->priv = fb it will cause null pointer access and crash.

since mmap may exist in block_operations, but truncate may not,
moving mmap beforee truncate could make three struct more compatible

- Add mmap into file_operations and remove it from ioctl definitions.
- Add mm_map structure definitions to support future unmapping
- Modify all drivers to initialize the operations struct accordingly
