imx6: Add imx6_src_get_boot_mode
For i.MX6, the bootmode determine code is part of spl_boot_device,
but there is might be a possibility for other part the code need to
check the desired boot mode for adding new functionalities like
modeboot env variable, or changing boot order etc.
So introduced imx6_src_get_boot_mode which actually reading the
boot mode register for desired modes.
More cleanup will be add in future patches.
