During the MMU development the MMU header files were left with unclean definitions: - MMU "version specific" definitions that were left in the mmu_general file - unused definitions This patch attempts, where possible, to keep definitions that can serve multiple MMU versions (but that are not tightly bound with specific MMU arch) in the mmu_general header file (e.g. different definitions for number of HOPs). Otherwise, move MMU version specific definitions (e.g. HOPs masks and shifts) to the specific MMU version file.
