Subject: [RESEND: PATCH v4 0/4] Add memory ownership switch support and enable mss rproc on msm8996

This patch does following
	1- Adds new scm call which helps in stage two translation of a memory region
	   so that memory ownership sharing and switching can be achieved on armv8 and later.
	2- Enable mss remoteproc on msm8996

Major changes since last patch:
	1- Refactored SCM API
	2- Changed SCM API Signature 
	3- Added cpu_to_le32() as and where required
	4- Elaborated documentation of new API added
	5- Refactored MSS rproc code which make the scm api call
	6- Refactored mss rproc code to first load all segments and then transfer ownership of
	   memory region to MSS for authentication and boot etc.
	7- Other Minor changes
	8- kbuild robot gave error so added dummy definition of __qcom_scm_assign_mem() in qcom_scm-32.c as well
