iwlwifi: mvm: add framework for specific phy configuration
Add framework for supporting specific PHY filter configuration,
which allows for application of various FW defined PHY filters
(one per antenna). Change phy_cfg_cmd to the new API (ver3).
Reading of configuration from platform's ACPI tables to be added
later when tables are defined.
