net: ethernet: oa_tc6: add OA_TC6_BROKEN_PHY quirk flag
Some MAC-PHY devices need custom MDIO bus access functions to work
around hardware issues. Add the OA_TC6_BROKEN_PHY quirk flag so drivers
can opt in to skip oa_tc6's internal PHY init and manage the PHY
themselves. When the flag is set, oa_tc6 skips MDIO bus registration,
PHY discovery and PHY connection, leaving these to the driver.
Drivers that do not set the flag retain the existing behavior. Update
lan865x and the framework documentation accordingly.
