These patches enable kernels to register the addresses of their log_buf
pointer with skiboot over the exiting OPAL APIs, which in turn allows
debug tools to discover where the host keeps it's secrets.
v2: Address Vasant's review
The first user of this feature will be the implementation of a 'pdbg
dmesg' command to read out the contents of the host kernel log buffer.
I've tested this on a romulus system.
