event/dlb2: fix advertized capabilities

This commit corrects the advertized capabilities reported by the DLB2 PMD.

Previously DLB2 reported supporting RTE_EVENT_DEV_CAP_QUEUE_QOS, but the
DLB2 hardware does not support such capability. This commit removes that
feature from the reported capabilities feature set.

Additionally, two capabilities that DLB2 does support were not being
reported in the capabilities feature set. This commit adds those.

RTE_EVENT_DEV_CAP_MULTIPLE_QUEUE_PORT = Event device is capable of
setting up the link between multiple queues and a single port. If the
flag is not set, the eventdev can only map a single queue to each
port or map a single queue to many port

RTE_EVENT_DEV_CAP_RUNTIME_PORT_LINK = Event device is capable of
configuring the queue/port link at runtime. If the flag is not set,
the eventdev queue/port link is only can be configured during
initialization

Finally, the file doc/guides/eventdevs/features/dlb2.ini has been updated
to match the capabilities actually reported by the PMD.
