devices: constify device pointers initialized at compile time

Browse source 
Many device pointers are initialized at compile and never changed. This
means that the device pointer can be constified (immutable).

Automated using:

```
perl -i -pe 's/const struct device \*(?!const)(.*)= DEVICE/const struct
device *const $1= DEVICE/g' **/*.c
```
