memory: make cpu_physical_memory_reset_dirty() take a length parameter

Browse source 
We have an end parameter in all the callers, and this make it coherent
with the rest of cpu_physical_memory_* functions, that also take a
length parameter.

Once here, move the start/end calculation to
tlb_reset_dirty_range_all() as we don't need it here anymore.
