Every PHY register access on STM32H7 spent 5 ms in up_mdelay(), so the boot-time autonegotiation link wait ran netinit at 44% CPU for 65 s with the net lock held whenever no ethernet cable was attached (PX4/NuttX#414, apache/nuttx#20067). Also picks up the two upstream stm32_mdio fixes for the lower-half cast and the Clause 22 write register field.
