Kernel+Userland: Remove supervisor pages concept

Browse source 
There's no real value in separating physical pages to supervisor and
user types, so let's remove the concept and just let everyone to use
"user" physical pages which can be allocated from any PhysicalRegion
we want to use. Later on, we will remove the "user" prefix as this
prefix is not needed anymore.
