[ Upstream commit a9149d243f259ad8f02b1e23dfe8ba06128f15e1 ]
The logic for checking required NVM sections was recently fixed in commit b3f20e098293 ("iwlwifi: mvm: fix NVM check for 3168 devices"). However, with that fixed the else is now taken for 3168 devices and within the else clause there is a mandatory check for the PHY_SKU section. This causes the parsing to fail for 3168 devices.
The PHY_SKU section is really only mandatory for the IWL_NVM_EXT layout (the phy_sku parameter of iwl_parse_nvm_data is only used when the NVM type is IWL_NVM_EXT). So this changes the PHY_SKU section check so that it's only mandatory for IWL_NVM_EXT.
