arm/raspberrypi: minimized mainline patch move MMU in front of application image and correct RPi2 boot on 4.11 branch.

This is minimized version of mainline patch

  arm/raspberrypi: move MMU in front of application image to respect variable memory size.

plus correction which has been part of other mainline patches.

This is end of series which allows 4.11 to boot on Raspberry Pi.

Closes #2782
