board: sunxi: enable status LED early

For some systems, such as the PinePhone, there is no way for the end
user to make sure the system is indeed booting before the boot script is
executed, which takes several seconds. Therefore, it can be useful to
provide early visual feedback as soon as possible.

In order achieve this goal, this patch initializes the status LED (if
configured) in the SPL.
