Subject: [PATCH v2 0/2] remoteproc: qcom: Use of_reserved_mem_lookup()

Use of_reserved_mem_lookup() instead of of_address_to_resource() inside
the Qualcomm remoteproc drivers. This has the advantage that it ensures
that the referenced memory region was really reserved and is not e.g.
status = "disabled".

Changes in v2:
- Add missing check for rmem (Bjorn)
- Add checks for rmem->size to ensure dynamic reserved memory was 
  really allocated
- Link to v1: https://lore.kernel.org/r/20230529-rproc-of-rmem-v1-1-5b1e38880aba@gerhold.net
