Subject: [PATCH v0 01/13] media: qcom: camss: Amalgamate struct resource with struct resource_ispif

There is no good reason to differentiate the two resource structures
here. As part of a general tidyup of the declaration and passing of
resources within in the CAMSS driver it will be advantageous to have
one unified resource structure.

The two structures are very similar anyway thus leading more credence
still to the argument there should be only one.
