These are changes to the cffdump output format.
MEMORY_BASE reports the address range we're using at the start
of the dump, which helps the postprocessors validate memory
writes.
HANG is emitted at the start of kgsl_postmortem_dump(), and can
be used by the postprocessors to stop when the hang occurs.
