Add 'r' to register name r2 in kvmppc_hv_enter.
Also update comment at the top of kvmppc_hv_enter to indicate that R2/TOC is
non-volatile.

This cleans up kvmppc_load/save_fp. It removes unnecessary isyncs. It also
removes the unnecessary resetting of the MSR bits on exit of kvmppc_save_fp.

Check that the OPAL_DUMP_READ token exists before initalising the elog

This avoids littering the OPAL console with:

Check that the OPAL_RTC_READ token exists before we use the OPAL RTC.
Refactors the code a little to merge error paths.
This avoids littering the OPAL console with:

Currently there is no way to generically check if an OPAL call exists or not
from the host kernel.
This adds an OPAL call opal_check_token() which tells you if the given token is
present in OPAL or not.

Fix ppc 32 build failure as reported here:
http://kisskb.ellerman.id.au/kisskb/buildresult/11663513/
The error is that pci_32.o was not being built for PPC_32. Fix error by adding
it in the Makefile. Tested using the ppc cross compiler.

This splits out the instruction analysis part of emulate_step() into
a separate analyse_instr() function, which decodes the instruction,
