mpc85xx: Update linker scripts for Freescale boards
* Move to using absolute addressing always. Makes the scripts a bit more
portable and common
* Moved .bss after the end of the image. These allows us to have more
room in the resulting binary image for code and data.
* Removed .text object files that aren't really needed
* Make sure _end is 4-byte aligned as the .bss init code expects this.
(Its possible that the end of .bss isn't 4-byte aligned)
