wifi: rtw88: disable ASPM and deep PS on ASUS TUF Gaming A15 FA506II
The RTL8822CE on the ASUS TUF Gaming A15 FA506II wedges during normal
use. The driver watchdog toggles PCIe ASPM while leaving power save;
the DBI read of the ASPM link-config register fails with -EIO, the PCIe
link becomes unstable, and the device drops off the bus, taking Wi-Fi
down until a cold power cycle:
rtw88_8822ce 0000:03:00.0: failed to read ASPM, ret=-5
rtw88_8822ce 0000:03:00.0: firmware failed to leave lps state
rtw88_8822ce 0000:03:00.0: mac power on failed
This is the same platform ASPM inter-operability problem already
handled for other machines through rtw_pci_quirks[]. Disabling PCI
ASPM and deep power save on this model stops the failure. Add a DMI
quirk so the workaround is applied automatically.
