Serge Semin 3ea8094c3b gpio: dwapb: Use optional-clocks interface for APB ref-clock
The common clocks kernel framework provides a generic way to use
an optional reference clock sources. If it's utilized there is no
need in checking whether the clock descriptor pointer is actually a
negative error at the moment of the prepare/unprepare clocks method
calling. So if the corresponding clock source is provided, then
getting an error shall actually terminate the device probe procedure.
If it isn't specified then the driver shall proceed with further
initializations.

We'll use the optional clocks getting method to handle the APB reference
clock, which can be provided for instance in the device of-node with
"bus" clock-name.
