Some hardware needs to config this delay to write one data block, because
the hardware needs more time to wear leveling and bad block manage.

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

- Fix DMA addressing issues within litex_sendsetup/litex_recvsetup
- Extend with handling specific to eMMC commands during init & use.
- Cleanup of 4-bit BUS handling for SD and eMMC
- For eMMC, Send CMD0 during init as per JEDEC v4.41 for pre-idle
MMC_CMD1 command is used to check whether card is MMC type (checked if
CONFIG_MMCSD_MMCSUPPORT is enabled). This commit inserts nxsig_usleep
wait if this check fails. This is to ensure the communication recovers
from invalid response as this may take some time on some platforms (
samv7 for example). Following command for SDHC check may fail if sleep
is not used.

mmcsd_removed will be called if the card is in invalid state.
This can happen if the card is bad, or vibrations causes a power
loss.
mmcsd_removed resets:
priv->capacity = 0; /* Capacity=0 sometimes means no media */
priv->blocksize = 0;
priv->probed = false;
priv->mediachanged = false;
priv->wrbusy = false;
priv->type = MMCSD_CARDTYPE_UNKNOWN;
priv->rca = 0;
priv->selblocklen = 0;
priv->widebus = false;
If blocksize is set to 0 will cause the log2 to result
in an infinate loop in some drivers.
IS_EMPTY will check for priv->type = MMCSD_CARDTYPE_UNKNOWN
and return ENODEV.
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

since rwbuffer isn't fully initiailized in mmcsd_slotinitialize.
BTW, if the cache is important for performance, it is better to
implement a general block cache and put in a common location.

This change makes it so that the timeout is set as part of the SDIO_WAITENABLE call instead of the SDIO_EVENTWAIT call. By doing so, you eliminate all opportunity for a race condition.

While testing PR #2989 on the H7 I noticed that the cards
were staying in 1-bit mode. The root cause was that the
scr read path was using DMA without an invlidate.
This was caused by CONFIG_ARCH_HAVE_SDIO_DELAYED_INVLDT,
but the sdmmc driver, did not use the delayed invalidate
nor would it work on 8 bytes.
The driver fully supported dcache mgt on runt buffers, but
the #ifdef CONFIG_ARCH_HAVE_SDIO_DELAYED_INVLDT blocked it.
Reviewing the PR that added CONFIG_ARCH_HAVE_SDIO_DELAYED_INVLDT
it may have been valid at the time. But after the dcache operations
we fixed. It is not necessary and offers no benefit.
