	    wdsc.c

Log Message:
Introduce abstraction layer for HPC registers and values, which addresses the
divergence between HPC revision 1.5 and revision 3.

The wdsc driver has been updated to reflect this layer (and may now work on
IP20).  The sq driver needs a bit more work before it can be committed.
