rtc + pci: CMOS clock with date command, PCI bus enumeration
- rtc.rs: read the PC RTC via CMOS ports 0x70/0x71 (UIP wait, BCD/12h normalization, century sanity-check with 2000+ fallback); boot prints the wall clock, shell gains 'date' - pci.rs: legacy config-space access (0xCF8/0xCFC) with full enumeration of buses 0-255; boot reports device count, shell gains 'pci' (lspci style listing with class names) - QEMU q35 verified: Q35 host bridge, stdvga, e1000, ICH9 LPC
