I think we can put the core of the TC implementation in arch/mips, and
then leave the rest in the per-port clock setup.  It's only a small
chunk of code, but I think it's better to have a small .c file in
arch/mips than exactly the same chunk of code duplicated over all MIPS
ports that have MIPS3 or greater CPUs.

I also think we might be better of using "mips_cp0_count" or similar for
the timercounter name.  We're using only part of the CP0 register space.
