Subject: [PATCH v2 2/9] remoteproc: core: Make the loaded resource table optional

From: Bjorn Andersson <bjorn.andersson@...ymobile.com>

Remote processors like the ones found in the Qualcomm SoCs does not have
a resource table passed to them, so make it optional by only populating
it if it does exist.
