When we added these callbacks the purpose of this was to allow drivers 
to do specific setup/teardown.

AFIAU, even-though if we add init(), SLIMbus would still call it just 
before or after status which to me is redundant ATM.
Its up to slim driver what it exactly whats to do with status, in some 
cases this can involve setting up the device.
