Kernel: Change Region allocation helpers

Browse source 
We now can create a cacheable Region, so when map() is called, if a
Region is cacheable then all the virtual memory space being allocated
to it will be marked as not cache disabled.

In addition to that, OS components can create a Region that will be
mapped to a specific physical address by using the appropriate helper
method.
