Revert "[OVN][Trunk] Add port binding info on subport when parent is bound"
This reverts commit 955e621167987626806128d259a29d4e62acf102.
Reason for revert: the port binding handling done in this patch is
incorrect and leads to issues during the cold migration process with
trunk ports in ML2/OVN.

Title:
[OVN][Trunk] The cold migration process is broken since patch 882581
Status in neutron:
Fix Released
Bug description:
The patch [1] is incorrectly handling the port binding of the
subports. This is a more complex operation than just updating the
"PortBinding" object. In order to change the port binding host ID, it
is needed to remove all "PortBinding" and "PortBindingLevels"
registers and create new ones pointing to the new host ID.
This patch is also breaking the cold migration process in ML2/OVN
environments with Trunk ports. The subports are not receiving the DHCP
information because OVN is not creating the DHCP flows that attend to
the DHCP requests. For example [2].
The recommended action is to revert the mentioned patch.
