6.12-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 80c2b651fe7fc82e1d1b3e4f9651095896a095f0 ]
This variable exists for the "common" (WiFi/BT) GUID, not the WiFi-only GUID. Fix that by passing the GUID to the function. A short-cut for the wifi-only version remains so not all code must be updated.
However, rename the GUID defines to be clearer.
Fixes: 09b4c35d73a5 ("wifi: iwlwifi: mvm: Support STEP equalizer settings from BIOS.")
