cpu/x86: Rename paging structure variables for clarity
The following variables have been renamed:
* PDPE_table -> PDPT (Page Directory Pointer Table)
* PDE_tables -> PDT (Page Directory Table)
This change improves the consistency and clarity of the code
as per AMD Architecture Programmer's Manual document.
PML4 -> PDPT -> PDT -> 2MB Physical Page
TEST=Able to build and boot google/rex64.
