Subject: [PATCH 09/11] iwlwifi: create device configuration header file

From: Johannes Berg <[email protected]>

The iwl-shared.h header file will be going away
soon. There isn't much left in it that we keep,
other than the device configuration declarations.
Move those out now to a new iwl-config.h header.
iwl-cfg.h seemed like a possible alternative but
those declarations will later live in the PCIe
transport code.
