x86-32, mm: Add an initial page table for core bootstrapping
This patch adds an initial page table with low mappings used exclusively for booting APs/resuming after ACPI suspend/machine restart. After this, there's no need to add low mappings to swapper_pg_dir and zap them later or create own swsusp PGD page solely for ACPI sleep needs - we have initial_page_table for that.
