W25QxxxJV NOR memories are backward compatible with older Winbond´s
generations and thus can also be supported here. This essentially brings
the support for generic SPI to W25QxxxJV memories as w25qxxxjv.c file only
supports QSPI communication.

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

1 Gbit W25Q01JV flash uses two 512 Mbit dies. This requires specific
operations in the driver in order to support the entire 1 Gbit region.
This commit adds dual die support for W25Q01JV flash.
Generally the driver has to switch active dies when die specific read from
status register is required (therefore before read, write, erase and when
checking if write status register was successful).

W25QXXXJV_WRITE_STATUS_2 register uses just first byte therefore all
operations has to be done in priv->cmdbuf[0]. Previous priv->cmdbuf[1]
caused QuadSPI mode not being enabled.

follow how Linux report the correction information from ecc:
http://www.infradead.org/pipermail/linux-mtd/2012-March/040305.html
since this information is very useful to file system(e.g. yaffs, ubi/buifs)
which is specially designed for nand flash.

Current driver supports MTDIOC_BULKERASE ioctl that erases the entire
device. The added ioctl MTDIOC_ERASESECTORS adds possibility to erase
just sectors defined by the user.
This is similar to MEMERASE call in Linux kernel.

since mmap may exist in block_operations, but truncate may not,
moving mmap beforee truncate could make three struct more compatible
Signed-off-by: Xiang Xiao <xiaoxiang@xiaomi.com>
- 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
