That won't work. the _wait() helpers are made to wait on self-clear (SC)
bits, i.e. looping until they are cleared to zero.

Here we want the opposite.

I will keep this existing wait loop for the moment and work soon on a
new patchset to rework the wait routines. We need a generic access to
test a given value against a given mask and wrappers for busy bits, etc.

That is better indeed.
