When booting the am3517-evm, the following message appears:
SPL: Please implement spl_start_uboot() for your board
SPL: Direct Linux boot not active!
This patch implements spl_start_uboot to clear this message
and allow device to know if it should boot U-Boot or kernel.
Fixes: 1c6b6f383a41 ("ARM: am3517_evm: Enable Falcon Mode")
