Need to enable MCP23S08 I/O expanders to manage Ethernet phy
reset in STM32MP135F-DK board
STMMAC driver defer is not silent, need to put this config in
built-in to avoid huge of Ethernet messages

PHY in capitals.

This second sentence is not correct, you are not enabling this GPIO 
controller driver to silence a warning, you are enabling this driver to 
let the PHY driver release the PHY from reset.
