* Add invensense3_456 driver for ICM45686 IMU
* Add support for 9th SPI slave
* Add SPI_SLAVE9 with PG01 as Chip Select on Cube Orange
Used in the Cube Orange Plus LTS / "shiny" release for the non-isolated IMU (on SPI bus 1)
* Add cube_orangeplus_lts board with new ICM45686 IMUs
Add two new items in module's dependency:
- recommends: a recommended module tells the sorting algo that if the module is found, it should be sorted accordingly. It is useful for optional dependencies, like shell or mission in some modules
- suggests: if a functionality is not provided by the user, a module can suggest a list of modules that can provide them. It is a convenient way to have "default" modules.
As a result the former autoload node is removed and replaced by suggested modules.
There is no longer a separated FBW in normal operation for fixedwing,
only a single AP task/thread.
The code for main_ap is now factorized for all firmwares.
Dual MCU support (separated AP and FBW) is still possible, based on the
rotorcraft implementation and intermcu pprzlink messages. Relevant code
is also factorized and available in all firmwares.
The recovery mode (in case of hard fault) is still available for
fixedwing with ChibiOS implementation.
Only intermcu_uart is supported at the moment. Other options (spi/can)
might be added back in the future if really used.
Some other evolution are made:
- in the radio_control and actuators modules, now integrated to AP and
using ABI messages
- the message parsing on datalink event (defined in module) that is now
properly filtering the messages based on their class and allowing to
have multiple callbacks for the same message
- cleaning the part of code that were using the old intermcu fixedwing
interface
