misc: alcor_pci: Use PCI core to manage ASPM instead of open-coding

"priv->ext_config_dev_aspm" was never set to a non-zero value.  Therefore,
alcor_pci_aspm_ctrl(priv, 1) did nothing, and alcor_pci_aspm_ctrl(priv, 0)
always disabled ASPM in the device and the upstream bridge.

The driver disabled ASPM in alcor_pci_probe() and alcor_resume(), so it's
possible the device doesn't work well when ASPM is enabled.

Remove all the ASPM-related code and replace the alcor_pci_aspm_ctrl(0)
calls with pci_disable_link_state(pdev, PCIE_LINK_STATE_L0S |
PCIE_LINK_STATE_L1), which asks the PCI core to disable ASPM.
