One of the four communication methods uses a DAC for analog signal sharing. This commit implements a first non-tested version of this feature.

Four files were modified to implement this feature:
- The low layer dac_configuration.h and .cpp: These files allow access to the dac module and can set any dac to constant value mode. The constant value can also be set.
- The HardwareConfiguration API: They give access to the low-leve configuration file to the user.

This MR updates the code used to acquire Zephyr device structures, in order to get rid of the `device_get_binding()` calls.

This allows to ensure statically (at compile time) that the drivers used by the code are correctly referenced wrt. drivers names in device tree, and to prevent code from using devices that are not enabled in device tree.

There was an error on the code for the inversion of the legs for two modes: independent and inverter. This patch corrects this issue.

The inverter mode had a problem on the `hrtim_configuration.c` file, the second leg was inverter and not the first.
The independent mode had a problem on the `HardwareConfiguration.cpp` file, the sencond leg was inverter and not the first.

It is necessary to properly control the min and max duty cycle of the hrtim. Our code already does that, but it is not efficient neither does it give the possibility for the user to dynamically set other min/max values. This patch solves that.

It is also necessary to give the user the possibility of setting the frequency of the HRTIM. This patch solves that at the leg driver level and provides the user with an access point.

Both the frequency and the min/max duty cycles are set by default at 200kHz and 0.1/0.9 respectively.

Updates the hardware configuration to allow using the gpio api to drive the power drivers for high side mosfets.

On the gpio side, the user now seamlessly activates the high side when activating the legs.
On the adc side, the user can now set the point of measurement with a float from the main.cpp for better control of the measurement moment.

This commit is a patch to address the issue of the Twist v1.1.2 board whose HRTIMA signals have been inverter in routing.

This commit defines a new hardware version, the TWIST_V_1_1_2.
This hardware version is then used to set up the control initialization sequence of the power legs, applying the necessary changest to leg 1 whose timer signals have been reversed in routing.
There is also a correction on the hrtim_init_independent_mode functino that initializes the pwm_phase_shift variable as well as their leg dependent equivalents.
This initalization is necessary to use the hrtim_interleaved_pwm_update function which uses the phase_shift variable when updating the duty cycle of interleaved buck and boost applicaitons.

This merge request corrects a small glitch on the trigger for the ADC for the O2 board.

This was changed some time ago. It did not work when tested in practice.

- The ADC 2 event necessary to trigger conversion was wrongly set for the spin board and measurements were not working.
- The gain and offset functions for V2 and i2 were not writing at the correct place on the gain table

The old version of the SPIN board required inverting the RX/TX of the serial port. The new version does not need this inversion.

This commit corrects a bug on the board version and allows choosing the correct SPIN version.

Provide a new communication API that rely on Thingset over CAN.
As the module relies on a third-party module that has to be downloaded, it is not enable by default.

The HRTIM still lacks some functions needed for a fine management of the PWM generation. This PR adds several functions. 

Deadtime management
The deadtime can now be managed separately from the rising and falling edges.

Phase shifting
The phase of the second leg can now be updated dynamicall

Bug fixes: 
Readable Independent mode
The independent mode can now be set as buck or boost instead of true or false, making it more readable.

Extra features: 
There is now a board version support for the SPIN board

Rewrote hrtim driver with LL APIs. Added Up-down mode (center aligned PWM) for buck, boost and independent mode. Corrected initialization errors for independent mode.

Add capability for finer configuration of HRTIM ADC event generation; Separate event generation postscaler.

Add ability to set discontinuous mode on ADCs; Add support for various trigger sources from HRTIM to ADCs.

New device tree organization, not based on Nucleo dts.
