These are currently the same as __PPC_RA/B/S/T but we'll wrap them
soon.

ix of both generated and non-generated with the same
code, so just convert all these to use the ___PPC_R versions which
won't enforce R usage later.

Enforce the use of R0-R31 in macros where possible now we have all the
fixes in.
R0-R31 macros are removed here so that can't be used anymore. They
should not be defined anywhere.

Some macros use RA where when RA=R0 the values is 0, so make this
the enforced mnemonic in the macro.
Idea suggested by Andreas Schwab.

The following added support for powernv but broke pseries/BML:
1f1616e powerpc/powernv: Add TCE SW invalidation support
TCE_PCI_SW_INVAL was split into FREE and CREATE flags but the tests in
the pseries code were not updated to reflect this.

Benh,

s to put the IPIs on one core (CPU0&1) and lan0 and
ibmvscsi on the other core (CPU2&3). This is suboptimal as we want lan0
and ibmvscsi to be on separate cores and IPIs to be ignored.
When irqblance attempts writes to the IPI smp_affinity (ie.
/proc/irq/16/smp_affinity in the above example)
