Right now, the hwcomposer hidl hal is unable to figure out where
to get the hidl mapper implementation.

It is expected that all graphics composer objects will need this
permission. The interfaces are written to work together with the
"IMapper" being the same-process ("sphal") component and the
"IComposer" interface being the binderized compoenent.

granted the same set of rules can be deleted.
