cpu/x86: Add 1GiB pages for memory access up to 512GiB
Current pagetable implementation allows memory access up to 4GiB using
2MiB pages. If user wants to access more than 4GiB with a 2MiB page it
will require more pagetable entries. By using a 1GiB page table, users
can access more than 4GiB of memory while reducing the number of
pagetable entries. This patch enables memory access up to 512GiB through
1GiB pages by selecting USE_1G_PAGETABLES in Kconfig.
TEST: Verified in 64bit mode boot and access above 4GiB
