wifi: mt76: transform aspm_conf for pci_disable_link_state

Browse Source 
commit b478e162f2 ("PCI/ASPM: Consolidate link state defines") changed
PCIE_LINK_STATE_L0S (1) to (BIT(0) | BIT(1)). PCI_EXP_LNKCTL_ASPM_L0S (1)
and PCI_EXP_LNKCTL_ASPM_L1 (2) are no longer matched with
PCIE_LINK_STATE_L0S (3) and PCIE_LINK_STATE_L1 (4).

On the platform enabling ASPM L0s and L1, mt76_pci_disable_aspm is not able
to disable L1. Fix this by transforming aspm_conf to pcie link state.
