ata: ahci: Add Intel Alder Lake-P AHCI controller to low power chipsets list 



Intel Alder Lake-P AHCI controller needs to be added to the mobile
chipsets list in order to have link power management enabled. Without
this the CPU cannot enter lower power C-states making idle power
consumption high.
