From: Moni Shoua <monis@xxxxxxxxxxxx>
ODP support for XRC transport is not enabled by default in FW,
so we need separate ODP checks to enable/disable it.
While that, rewrite the set of ODP SRQ support capabilities in way
that tests each field separately for clearness, which is not needed
for current FW, but better to have it separated.
