Some SD card connectors do not have separate card detection pin. In that
case card detection has to be done on CD/DAT3 data line. This means
software (i.e. architecture level driver) has to take care of pin
configuration switching (pin has to be set as data pin in case of
transfer and as interrupt card detection pin when there is no action
on data line).
This commit adds CD/DAT3 line card detection support for SAMv7 MCU.

The class device only handles descriptor information specific to the class,
and shared descriptor information is passed through parameters and
handled by the composite driver.

When I try to set priorities in certain programs, such as init_priority(HIGH_PRIORITY), I've noticed that during linking, there's no guarantee that the programs will be compiled in the sequence I've specified based on priority. This has led to some runtime errors in my program.
I realized that in the ld file, when initializing dynamic arrays, there's no assurance of initializing init_array.* before init_array. This has resulted in runtime errors in the program. Consequently, I've rearranged the init_array.* in the ld file of NuttX to be placed before init_array and added a SORT operation to init_array.* to ensure accurate initialization based on priorities during linking.
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.
Move SCU-specific ak09912 sensor into spresense board layer.
Rename a function name to register SCU sensor driver
from ak09912_register to ak09912_scu_register.
