Add private HCALL to inform updated RTAS base and entry
This patch adds a private HCALL to inform qemu the updated
rtas-base and rtas-entry address when OS invokes the call
"instantiate-rtas". This is required as qemu allocates the
error reporting structure in RTAS space upon a machine check
exception and hence needs to know the updated RTAS.
Enhancements to qemu to handle the private HCALL, prepare
error log and invoke machine check notification routine
are in a separate patch.
