In order to achieve better scalability, change the stride
from pixel mode to byte mode.For example, in the case of RGB888
mode with 466 pixels in width and a 4-byte aligned buffer,it is
only necessary to extend the buffer of one line from 1398 bytes
to 1400 bytes, instead of extending it to 1404 bytes.

The BIT macro is widely used in NuttX,
and to achieve a unified strategy,
we have placed the implementation of the BIT macro
in bits.h to simplify code implementation.

3 wire interface for ST7789 LCD controller does not use CMD/DATA pin to
specify whether data or command is send but uses 9th bit of SPI transfer.
This commit adds support for 3 wire interface to ST7789 controller.

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

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

The write has to be in number of bytes per pixel as single SPI exchange
is used to identify single pixel write by the ST7789 driver. By issuing
only byte writes the displayed color is corrupted as it is stripped.
This fix consist of setting SPI to correct number of exchanged bytes and
then passing correctly number of words to the SPI exchange.
This also covers usage of st7789_wrram in st7789_putrun as that one was
passing just number of pixels as size but the correct is now number of
bytes.
In the past, header file paths were generated by the incdir command
Now they are generated by concatenating environment variables
In this way, when executing makefile, no shell command will be executed,
it will improve the speed of executing makfile
