NFC: nci: Add firmware download support
A simple forward for firmware download (i.e. sending a new firmware to the NFC adapter) from the NFC subsystem to the drivers. This feature is required to update the firmware of NXP-NCI NFC controllers but can be used by any NCI driver. This feature has been present in the HCI subsystem since 9a695d.
