Subject: [PATCH] ACPI: Kill overly verbose "throttling states" log messages

I was recently lucky enough to get a 64-CPU system.  The processors
actually have T-states, so my kernel log ends up with 64 lines like:

    ACPI: Processor [CPU0] (supports xx throttling states)

This is pretty useless clutter because

 - this info is already available after boot from
   /proc/acpi/processor/CPUnn/throttling

 - there's also an ACPI_DEBUG_PRINT() in processor_throttling.c that
   gives the same info on boot for anyone who *really* cares.

So just delete the code that prints the throttling states in
processor_core.c.
