[PATCH] sh: Cleanup struct sh_cpuinfo for clock framework changes

Browse source 
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.
