[PATCH net-next 5/7] net: ipa: use version based configuration for SC7180

From: Alex Elder
Date: Sun Mar 28 2021 - 13:34:36 EST


Rename the SC7180 configuration data file so that its name is
derived from its IPA version.

Update a few other references to the code that talk about the SC7180
rather than just IPA v4.2.
