From: Rob Herring <robh@xxxxxxxxxx>
The sp804 clocks may be specified in DT, but the kernel may still be using
legacy clocks. This is handled if a single clock for sp804 is present,
but not when 3 clocks are present.
This prevents Versatile platforms from breaking when the DT has clocks
added.

v2:
- New patch necessary to handle DT with 3 clocks in sp804 node and still
use the legacy non-DT clocks.
