sh: hw-breakpoints: Add preliminary support for SH-4A UBC.
This adds preliminary support for the SH-4A UBC to the hw-breakpoints API. Presently only a single channel is implemented, and the ptrace interface still needs to be converted. This is the first step to cleaning up the long-standing UBC mess, making the UBC more generally accessible, and finally making it SMP safe. An additional abstraction will be layered on top of this as with the perf events code to permit the various CPU families to wire up support for their own specific UBCs, as many variations exist.
