ARM: imx: Decouple mccmon6's SPL and u-boot proper code

The mccmon6 has been used a "mixed" approach between SPL and
U-Boot proper sources.

This commit decoupes SPL and u-boot proper, which allows clear
distinction between those two code bases and facilitates
conversion to DM/DTS on this particular board.
