Update PCIE PHY sequence as per hardware setting reference(HSR) specifically, PCIE RC Config sequence(PCIE RC Cfg Seq). Key changes: - Add RX1-specific overrides applied after common RX settings - Update TX lane mode register (LANE_MODE_3: 0x90 -> 0x51) - Modify RX calibration and equalization parameters - Adjust RX signal detection level (0xAA -> 0xCC) - Add NVME_PLN_GPIO definition for Power Loss Notification The changes ensure proper PHY initialization for PCIe Gen 4 link establishment and improve signal integrity.
