PCI/ASPM: Clear the correct bits when enabling L1 substates
In pcie_config_aspm_l1ss(), we cleared the wrong bits when enabling ASPM L1
Substates. Instead of the L1.x enable bits (PCI_L1SS_CTL1_L1SS_MASK, 0xf), we
cleared the Link Activation Interrupt Enable bit (PCI_L1SS_CAP_L1_PM_SS,
0x10).
Clear the L1.x enable bits before writing the new L1.x configuration.
