rtw88: allows to enable/disable HCI link PS mechanism
Different interfaces have its own link-related power save mechanism.
Such as PCI can enter L1 state based on the traffic on the link, and
sometimes driver needs to enable/disable it to avoid some issues, like
throughput degrade when PCI trying to enter L1 state even if driver is
having heavy traffic.
For now, rtw88 only supports PCIE chips, and they just need to disable
ASPM L1 when driver is not in power save mode, such as IPS and LPS.
