net: dsa: hellcreek: Allow PTP P2P measurements on blocked ports

BugLink: https://bugs.launchpad.net/bugs/1959376
[ Upstream commit cad1798d2d0811ded37d1e946c6796102e58013b ]

Allow PTP peer delay measurements on blocked ports by STP. In case of topology
changes the PTP stack can directly start with the correct delays.

Fixes: ddd56dfe52c9 ("net: dsa: hellcreek: Add PTP clock support")
