This adds userspace consumer for common clock.

This driver is inspired from Userspace regulator consumer
(REGULATOR_USERSPACE_CONSUMER) and it is useful for test purposes and
some classes of devices that are controlled entirely from user space.

Whether the kernel handles a clock or userspace does should have nothing 
to do with DT. Plus DT does not expose many of the clocks, so any 
debug feature needs to expose all clocks and be independent of DT.

Beyond debug, I don't think we should be exposing clock control to 
userspace.

Agreed. Plus, the userspace regulator consumer doesn't have any
DT binding for it, so I don't see why we would have a DT binding
for the clk one.
