[PATCH v3 1/6] pds_core: add support for quiet devcmd failures

["Nikhil P. Rao" <nikhil.rao@amd.com>]

From: Brett Creeley <brett.creeley@amd.com>

Currently there aren't any use-cases that require special handling
on whether or not to print devcmd failures. Specifically
non-generic failures, i.e. not supported failures. Add support to
allow these messages to be suppressed. This will be used when
adding support to negotiate PDS_CORE_IDENTITY_VERSION_2.
