Subject: [PATCH 47/57] phc2sys without -w option.
Fix bad clock and pmc initialization when -w command argument
is not provided.
The pmc agent must be created and mapped to a clock source even
in cases the -w (wait for ptp4l) option is not used.
Test plan:
PASS: Verify phc2sys initializes without -w argument.
PASS: Verify phc2sys initializes with two ptp4l interfaces
configured.
