Andre Mauricio Zelak cfe25f0193 Fixed event port id map 
Fixed the port id map in the Port Data Set event handling. The port id
is composed by port number and node index after the HA implementation.

Code tidying. As definition, the port id and the port number are
different. An existing port number variable was rennamed to
prevent missinterpretation.

Code tidying. The HA node state change processing was disabled
when HA feature is not enabled.

Test plan:
PASS: Verify the phc2sys executable recognizes the port in the port
state change event, when -a configuration option is used
PASS: Verify the events in the HA scenario are being recognized

Subject: [PATCH 34/56] clock: Rename UDS variables to read-write.
In preparation for a new read-only UDS port, rename variables of the
current UDS port to make it clear it is read-write, as opposed to
read-only.
