soc: qcom: add secure processor communication (spcom) driver 



This driver supports communication with secure processor subsystem
(SPSS) over rpmsg and ungerlying glink transport layer. The
communication is based on using shared memory and interrupts.
Add snapshot for spcom driver from msm-4.19 commit b3159f82fb1b
("soc: qcom: spcom: fix active pid clean up").

	   SPCOM driver allows loading Secure Processor Applications and sending

	   messages to Secure Processor Applications. SPCOM implements logic of RPMSG

	   client of SPSS edge. SPCOM provides interface to both user space app and

	   kernel driver. It is using glink as the transport layer, which provides

	   multiple logical channels over single physical channel. The physical layer

	   is based on shared memory and interrupts. SPCOM provides clients/server API

	   although currently only one client/server is allowed per logical channel.
