Add drv8323 and drv8320 drivers (untested)

[Moddingear]

As described, it's untested but compiles.
I have some doubts about bit order in the structures.

I started with the code from the drv8316, but it has diverged a lot. Some similarities are to be expected, but instead of writing a ton of boilerplate, I made macros for it.

Also maybe the interrupt handler of the drv8316 should be removed.
