Disable PCIe ASPM unconditionally for MT7927. The CONNINFRA power domain and WFDMA register access are unreliable with PCIe L1 active, causing throughput to drop from 1+ Gbps to ~200 Mbps. Disable runtime PM and deep sleep for MT7927. The combo chip shares a CONNINFRA power domain between WiFi (PCIe) and BT (USB). SET_OWN/CLR_OWN transitions on the LPCTL register crash the BT firmware, requiring a full power cycle to recover. PM enablement will be addressed in a follow-up once safe power state transitions are determined.
