Luca Coelho e0d9727c11 iwlwifi: pcie: fix SPLC structure parsing 
The SPLC data parsing is too restrictive and was not trying find the
correct element for WiFi.  This causes problems with some BIOSes where
the SPLC method exists, but doesn't have a WiFi entry on the first
element of the list.  The domain type values are also incorrect
according to the specification.

Fix this by complying with the actual specification.

Additionally, replace all occurrences of SPLX to SPLC, since SPLX is
only a structure internal to the ACPI tables, and may not even exist.

Fixes: bcb079a14d ("iwlwifi: pcie: retrieve and parse ACPI power limitations")
