We already used to support the external proxy facility of FSL MPICs,
but only implemented it halfway correctly.
This patch adds support for
* dynamic enablement of the EPR facility
* interrupt acknowledgement only when the interrupt is delivered
This way the implementation now is closer to real hardware.

Book E does not play games with certain bits of xSRR1 being MSR save
bits and others being error status. xSRR1 is the old MSR, period.
This was causing things like MSR[CE] to be lost, even in the saved
version, as soon as you take an exception.
rfci/rfdi/rfmci are fixed to pass the actual xSRR1 register contents,
rather than the register number.
Put FIXME comments on the hack that is "asrr0/1". The whole point of
separate exception levels is so that you can, for example, take a machine
check or debug interrupt without corrupting critical-level operations.
The right xSRR0/1 set needs to be chosen based on CPU type flags.

The BookE variant of MSR_SF is MSR_CM. Implement everything it takes in TCG to
support running 64bit code with MSR_CM set.

Add an explicit CPUPPCState parameter instead of relying on AREG0
and rename op_helper.c (which only contains load and store helpers)
to mem_helper.c. Remove AREG0 swapping in
tlb_fill().
Switch to AREG0 free mode. Use cpu_ld{l,uw}_code in translation
and interrupt handling, cpu_{ld,st}{l,uw}_data in loads and stores.

Move exception helpers from helper.c to excp_helper.c and
make cpu_dump_rfi() static.
