[PATCH iproute2] dpll: fix man page correctness issues

[Ivan Vecera <ivecera@redhat.com>]

Fix several inaccuracies in dpll.8 man page:
- Remove bogus "holdover" and "freerun" from operating modes list,
  only "manual" and "automatic" modes exist in the DPLL API
- Fix typo "locked-ho-ack" -> "locked-ho-acq" in lock status list
- Add missing device show output fields: lock-status-error,
  clock-quality-level, mode-supported, phase-offset-monitor and
  phase-offset-avg-factor
- Add missing pin show output fields: panel-label, package-label,
  fractional-frequency-offset and esync-pulse
- Remove non-existent exit codes 2 and 255, the tool only returns
  0 (success) or 1 (failure)
- Use canonical enable/disable for phase-offset-monitor to match
  the tool's help text

Fixes: 656cfc3ce05b ("dpll: Add dpll command")
