From: Lee Jones <lee.jones@xxxxxxxxxx>
Currently, when a remote processor does not require resources, the
platform-specific remoteproc driver has to create a fake resource
table in order to by-pass the strict checking. But there is no hard
requirement for a remote processor so require or support shared
resources. This patch removes the strict checking and skips
resource table related operations if none is provided.
