wifi: iwlwifi: acpi: check the size of the ACPI PPAG tables

Browse source

We need to make sure we don't have a buffer overflow while reading the
PPAG tables from ACPI into the firmware runtime object.
Add an ACPI specific define for the number of chains in order to
decouple the ACPI layout from the other objects.
