remoteproc: introduce version element into resource type field

The current remoteproc core has supported only 32-bit remote
processors and as such some of the current resource structures
may not scale well for 64-bit remote processors, and would
require new versions of resource types. Each resource is currently
identified by a 32-bit type field. Introduce the concept of version
for these resource types by overloading this 32-bit type field
into two 16-bit version and type fields with the existing resources
behaving as version 0 thereby providing backward compatibility.

The version field is passed as an additional argument to each of
the handler functions, and all the existing handlers are updated
accordingly. Each specific handler will be updated on a need basis
when a new version of the resource type is added.

An alternate way would be to introduce the new types as completely
new resource types which would require additional customization of
the resource handlers based on the 32-bit or 64-bit mode of a remote
processor, and introduction of an additional mode flag to the rproc
structure.
