Put this config in built-in like STMMAC to avoid huge of Ethernet

You're not avoiding any error/defer/messages here, you simply need to
enable the MCP23S08 GPIO controller driver, so the kernel can use the
GPIO provided by that driver instance to release the ethernet PHY from
reset on STM32MP135F-DK, that's all.
