From: "Bolarinwa O. Saheed" <refactormyself@gmail.com>
To validate and set link latency capability, `struct aspm_latency` and related members defined within `struct pcie_link_state` are used. However, since there are not many access to theses values, it is possible to directly access and compute these values.
Doing this will also reduce the dependency on `struct pcie_link_state`.
The series removes `struct aspm_latency` and related members within `struct pcie_link_state`. All latencies are now calculated when needed.
VERSION CHANGES: - v2: » - directly access downstream by calling `pci_function_0()` » instead of using the `struct pcie_link_state`
- v3: » - rebase on Linux 5.15-rc2
- v4 (this version) - Create a seprate path to move pci_function_0() upward
MERGE NOTICE: These series are based on » 'commit e4e737bb5c17 ("Linux 5.15-rc2")'
