151: Tock 2.0: touch api and example app for 2.0 API r=phil-levis a=alexandruradovici

This pull request adds the touch driver API and example.

It should close #126

156: Tock 2.0/rng: fix rng_sync yield for callback r=phil-levis a=lschuermann

### Pull Request Overview

This fixes a bug introduced with the Tock 2.0 RNG migration, where the `rng_sync` function would return prior to `yield`ing for the callback to occur.

I did test the previous PR (#146), although I've hit the bugs of #154 so my testing methodology wasn't as thorough as I'd hoped it would be (had limited access to ARM boards then).

Fixes: f284e25 ("Update RNG to Tock 2.0 system call interface")

### Testing Strategy

This pull request was tested by running the `rng` and `number_guess_game` test apps on a Hail.


### TODO or Help Wanted

157: Tock 2.0: sound pressure API r=phil-levis a=alexandruradovici

This PR adds the user space API for the sound pressure driver (tock/tock#2364) and adds the sound pressure driver to the example sensors app.

158: Tock 2.0: ninedof driver API r=phil-levis a=alexandruradovici

The PR updates the ninedof driver API.

159: Tock 2.0: nonvolatile storage & app flash driver r=phil-levis a=lschuermann

### Pull Request Overview

This pull request ports both the nonvolatile storage driver and the app flash driver to the Tock 2.0 system call interface. It's the counterpart to tock/tock#2362.

It furthermore adds a `BADRVAL` error, as indicated in the Tock 2.0 TRD. Drivers can return this error code (with an assigned value of `-1024`) in case a kernel driver returns an unexpected variant which they do not know how to handle.

### Testing Strategy

This pull request was tested by running the `nonvolatile_storage` and `app_state` tests on the accompanying [kernel PR](tock/tock#2362).

2364: Tock 2.0: update sound pressure driver r=phil-levis a=alexandruradovici

### Pull Request Overview

This pull request update the sound pressure driver to the new 2.0 driver API.

Using the new API requires increasing the kernel stack size (it faults with stack overflow otherwise).

### Testing Strategy

This pull request was tested using a MicroBit v2.

### TODO or Help Wanted

N/A

### Documentation Updated

- [x] Updated the relevant files in `/docs`, or no updates are required.

### Formatting

- [x] Ran `make prepush`.
