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.
If scheduling occurs in file_fsync,
fl_lock may be released, and an error may
occur when calling nxmutex_unlock

This commit adds support for galvanic isolated ISO1H812G SPI expander.
Both single pin and multiple pin writes are supported.

Current implementation of QSPI in SPI mode was available only for MCUs
that do not have standard SPI at all. MCUs with both QSPI and SPI can
however also use QSPI in SPI mode and thus have one more SPI bus. This
commit adds required defines and config options to support QSPI in SPI
mode for all SAMv7 MCUs.

Calculate how long an I2C transation will take in microseconds, and use
this as the timeout for mpfs_i2c_sem_waitdone.
The reason for doing this is not to keep an i2c bus reserved for the full
1 second timeout, if e.g. a sensor is not on the bus / is faulty and
non-responsive. Reading the other sensors will be blocked for a relatively
long time (1 second) in this case. This fixes such behavior.
update LIBFDT to LIBC_FDT
update CONFIG_LIBFDT_DTC_VERSION to CONFIG_LIBC_FDT_DTC_VERSION
move dtc source code to fdt/dtc
move version_gen.h from apps/system/fdt to current dir

This patch starts to implement the ability to build Meadow.OS for the Meadow F7 board with the NuttX mainline. It will be followed by more patches, progressively enabling full Meadow.OS functionality. This configuration is a work in progress.
The Meadow.OS source code is needed to build this configuration. Meadow.OS is being open-sourced under the Apache 2.0 license. A prototype of the source code release and integration with NuttX is at https://github.com/WildernessLabs/Meadow.OS/tree/prototype
This is the second revision of this patch, as the first one (https://github.com/apache/nuttx/pull/9997) was causing build issues on NuttX CI and was reverted.
This should only impact the Meadow F7 board configurations.
No testing to be done, as the configuration is under development.
