Right now the code relies on the bootloader to set up the interrupt mask
correctly. This usually works but let's make sure to do it explicitly to
guarantee it will always work.

You should first only set the mask on your board. We can then see if
it's something that should be done on other boards as well later.
Make sense, I'll only call this when the cd321x variant is probed then.
