soc: qcom: smem: Support reserved-memory description
Practically all modern Qualcomm platforms has a single reserved-memory
region for SMEM. So rather than having to describe SMEM in the form of a
node with a reference to a reserved-memory node, allow the SMEM device
to be instantiated directly from the reserved-memory node.
The current means of falling back to dereferencing the "memory-region"
is kept as a fallback, if it's determined that the SMEM node is a
reserved-memory node.
The "qcom,smem" compatible is added to the reserved_mem_matches list, to
allow the reserved-memory device to be probed.
In order to retain the readability of the code, the resolution of
resources is split from the actual ioremapping.
