Subject: [PATCH] [mips] add some (temporary, I hope!) mips24k/mips74k hwpmc
 modules.

Ideally we'd have a top level hwpmc module with the shared bits, then
cpu specific glue as needed.  However, on the MIPS side, there's no
probe code - {mips24k, mips74k, octeon} implement a set of methods
that hwpmc_mips.c expects.

So this populates separate modules with duplicate code.
Ew, but it does work.

This gets me off the hook - these work fine as copied into the relevant
mfsroot for mips24k/mips74k systems.

TODO:

* do it the "right" way in the future.  Note that modules/hwpmc/ does
  build fine on MIPS, it jusn't DO anything.  So it'd be nice to
  maybe call that "hwpmc_core" and then "hwpmc" can be the CPU/arch glue.
