bnxt: Implement ndo_get_port_parent_id()

BNXT only supports SWITCHDEV_ATTR_ID_PORT_PARENT_ID, which makes it a
great candidate to be converted to use the ndo_get_port_parent_id() NDO
instead of implementing switchdev_port_attr_get(). The conversion is
straight forward here since the PF and VF code use the same getter.

Since bnxt makes uses of switchdev_port_same_parent_id() convert it to
use netdev_port_same_parent_id().
