cpu/x86: Rename `PDE_table` to `PDPT` for 1 GiB page mappings
This commit fixes an incorrect variable name in the page table setup for 1 GiB pages. The label PDE_table was used when it should have been PDPT, as it represents a "Page Directory Pointer Table (PDPT)", not a "Page Directory Table (PDT) or PDE_Table". This change ensures correct nomenclature and consistency in the code. PML4 -> PDPT --------> 1GB Physical Page As per x86-64 specification, 1GB pages bypass the Page Directory Table (PDT) level of the page table hierarchy, mapping directly from the Page Directory Pointer (PDPT) Table to the physical page.
