imx6guf:linux-guf: Disable CONFIG_EARLY_PRINTK

SANTINO-LT is the first G&F iMX6 platform that uses a different UART
debug port, UART5 instead of UART2. It is not possible to use both port
settings together with early printk. Even though this is unfortunate,
we do not need the early printk feature enabled in production so diable
it here.

CONFIG_VT_HW_CONSOLE_BINDING and CONFIG_LEDS_TRIGGERS are still due to
default dependencies.
