## Summary Currently the mdio communication is part of the monolithic 'full netdevs'. This commit serves as an way to add modularity for the netdevs drivers. A new upperhalf/lowerhalf mdio device comes with this commit that manages the data transfer ofer mdio interface. It resembles the upperhalf/lowerhalf approach of the netdevs or i2c bitbang. ## Impact A new upperhalf mdio bus is now added as a set of **include/nuttx/net/mdio.h** and **drivers/net/mdio.c** files which "sets" the available mdio commands (read, write, reset). Acts as the bus "controller". It block the bus during the transaction and calls the apropriate lowerhalf function. A new lowerhalf mdio bus for the stm32h7 mcu family was added which implements the actual mdio transfers. A new Kconfig option was added MDIO_BUS in the drivers/net directory ## Testing This PR have low impact over the nuttx codebase. The new files are included to the build system based on the CONFIG_MDIO_BUS Currently, only stm32h7 has the new mdio bus. -- This is an automated message from the Apache Git Service.
