Subject: [PATCH net-next 4/7] net: ipa: switch to version based configuration
Rename the SDM845 configuration data file so that its name is
derived from its IPA version. I am not aware of any special IPA
behavior or handling that would be based on a specific SoC (as
opposed to a specific version of the IPA it contains).
Update a few other references to the code that talk about the SDM845
rather than just IPA v3.5.1.
