ata fixes for 6.10-rc2 

- Add a quirk for three different devices that have shown issues with
    LPM (link power management). These devices appear to not implement LPM
    properly, since we see command timeouts when enabling LPM. The quirk
    disables LPM for these problematic devices. (Me)
 
  - Do not apply the Intel PCS quirk on Alder Lake. The quirk is not needed
    and was originally added by mistake when LPM support was enabled for
    this AHCI controller. Enabling the quirk when not needed causes the
    the controller to not be able to detect the connected devices on some
    platforms.
