Unless there's some complication with representing them (mainly register
layouts that aren't representable with the language or *very* repetitive
blocks of registers) we should be adding any new sysregs to the sysreg
file rather than manually encoding them.  We're trying to move things
out of sysreg.h as much as possible.

For the above you can pick up the patch from my GCS series:

This is in Joey's POR series:

Unfortunately I'm not aware of anyone having already done the rest.
