The USB hub on STM32MP1 DHCOM boards needs to wait a bit longer until the USB Vbus is stable. Increase the USB power-good delay to 1 s.
This adds default-undefined STM32MP_BOARD_EXTRA_ENV variable into stm32mp15_common.h to reduce duplication in board-specific config files adding custom environment.
