powerpc/powernv: Add ultravisor message log interface
The ultravisor (UV) provides an in-memory console which follows the
OPAL in-memory console structure.
This patch extends the OPAL msglog code to initialize the UV memory
console and provide the "/sys/firmware/ultravisor/msglog" interface
for userspace to view the UV message log.
