feat(st): properly manage early console

The new flag STM32MP_RECONFIGURE_CONSOLE is managed in platform.mk.
It is used in stm32mp_setup_early_console() when calling
plat_crash_console_init(). This call is also under:
"#if defined(IMAGE_BL2)"
as this crash console init shouldn't be done by default in BL32.
