[U-Boot] [PATCH] rockchip: Turn on CONFIG_DEBUG_LL for firefly

[Ariel D'Alessandro]

CONFIG_DEBUG_UART is enabled in defconfig, but there's no Low-level
debugging functions implemented, so build fails because of undefined
references to `printch' in common/console.c.
In order to fix this, enable CONFIG_DEBUG_LL.
