fix(kernel): Fix PMM memory page table reservation, ATA driver timeout loops, and PCI probe order

Browse Source 
- Fix PMM memory map parsing: always reserve lower 8MB on x86_64 to protect bootloader, GDT, IDT, and PML4 page tables
- Fix ATA driver: add bounded timeouts to ata_wait_ready() and ata_wait_drq() to eliminate infinite busy loops
- Fix PCI bus initialization order: probe PCI devices before AHCI/NVMe/NIC storage and network drivers
- Implement missing pmm_get_total_pages() and pmm_get_usable_memory() getters
