dt-bindings: firmware: arm,scmi: Move arm,scmi-shmem to json schema

Move the SRAM and shared memory binding for SCMI into the existing
Generic on-chip SRAM. We just need to update the compatible list and
there-by remove the whole old text format binding for the same.

-SRAM and Shared Memory for SCMI
--------------------------------
-
-A small area of SRAM is reserved for SCMI communication between application
-processors and SCP.
-
-The properties should follow the generic mmio-sram description found in [4]
-
-Each sub-node represents the reserved area for SCMI.

-Required sub-node properties:
-- reg : The base offset and size of the reserved area with the SRAM
-- compatible : should be "arm,scmi-shmem" for Non-secure SRAM based
-              shared memory
