Includes the latest driver changes to match 1.0 HW changes, the new pinmux driver, and also a bump to the system clock frequency from 30 MHz to 40 MHz. The driver changes include updates to the I2C, EThernet, PWM and GPIO drivers, as well as board description file updates.
The updated I2C driver handles controller halts properly, and for good practice requires (via a `nodiscard` attribute) that the new Boolean result of the I2C's `blocking_write` function is not discarded. This commit hence simply adds checks to the existing demos that will debug log if an error occurs on these writes.
Sonata's updated GPIO driver correctly provides different struct for different GPIO devices. This updates Sonata's examples and exercises (with the exception of the automotive demo, which will be handled separately) to use the new drivers and names of devices from the board description file, and changes direct reads/writes to/from the `input` and `output` registers to match the new general/board GPIO mappings after things have moved in the hardware.
In the latest 1.0 hardware, the LCD has been changed to use a chip select (for its CS, DC and RST pins) and to use a PWM for its backlight. This commit updates the LCD library/driver to appropriately make use of the SPI driver intsead of the GPIO as it was using before, and to use the PWM for the LCD's backlight. The PWM is always set to 100, and for now the driver simply replaces existing functionality - there is no way to modify the PWM from the driver.
This was done using the following command: nix flake lock --update-input sonata-system The new revision for Sonata System is: d410c6692bae8b579ee1b9986dd7ad1ebe077a8b
