[RFC PATCH v3 0/3] PCI/ASPM: Remove struct aspm_latency

["Saheed O. Bolarinwa" <refactormyself@gmail.com>]

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(this version):
	- rebase on Linux 5.15-rc2

MERGE NOTICE:
These series are based on 
	'commit e4e737bb5c17 ("Linux 5.15-rc2")'
