wimax/i2400m: cache firmware on system suspend
In preparation for a reset_resume implementation, have the firmware image be cached in memory when the system goes to suspend and released when out. This is needed in case the device resets during suspend; the driver can't load firmware until resume is completed or bad deadlocks happen. The modus operandi for this was copied from the Orinoco USB driver. The caching is done with a kobject to avoid race conditions when releasing it. The fw loader path is altered only to first check for a cached image before trying to load from disk. A Power Management event notifier is register to call i2400m_fw_cache() or i2400m_fw_uncache() which take care of the actual cache management.
