colibri_vf: implement module type auto detection
Implement module type (e.g. VF50 vs. VF61) auto detection based on L2
cache availability. Set specific ARM core clock (e.g. 400 vs. 500 MHz)
as well as Linux machine id number.
While at it actually use memargs instead of hard-coded mem= value.
While at it fix sdboot command if initially booting U-Boot from NAND by
doing an explicit mmc part 0.
