[PATCH] sh: Cleanup struct sh_cpuinfo for clock framework changes
Now that the clock framework changes have been integrated, the manual clock accounting that was done in sh_cpuinfo can be dropped. Also correct a bug with running past the end of the CPU flags when there's a mismatch between the added flags and printed ones.
