  1. Bump CHERIoT RTOS to latest sonata branch. 

    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.

  2. Update demos to use updated I2C driver. 

    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.

  3. Update Examples/Exercises to use updated GPIO/PWM drivers 

    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.

  4. Update LCD library to use LCD CS and PWM instead of GPIO 

    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.
