arch-power: Add multi-mode debugging support
This adds multi-mode support for remote debugging via GDB
with the addition of the XML target description files for
both 32-bit and 64-bit variants of the Power architecture.
Proper byte order conversions have also been added.
MSR has now been modeled to some extent but it is still
not exposed by getRegs() since its a privileged register
that cannot be modified from userspace. Similarly, the
target descriptions require FPSCR to also be part of the
payload and hence, it has been added too.
