This is analogous to the kernel scheme where code describes a driver
with a static structure and then a helper macro registers that
driver with the core code.
In this case we have an 'ops' that is both the 'driver' and 'device'
ops.
This is preparation to add more steps to the device startup. Rework
all the providers to use this scheme.
