Kernel: Remove problematic memory mapping methods

Browse source 
mmap() & mmap_region() methods are removed from ACPI & DMI components,
and we replace them with the new MM.allocate_kernel_region() helper.

Instead of doing a raw calculation for each VM address, from now on we
can use helper functions to do perform those calculations in a neat,
reusable and readable way.
