firmware: Add firmware installation to modules_install, add firmware_install
For 'make modules_install', install any firmware required by the modules which are being installed. Also add a 'make firmware_install' target which doesn't depend on the configuration, but installs _all_ available in-kernel-tree firmware into $(INSTALL_FW_PATH), which defaults to /lib/firmware. This is intended for distributors to make arch-independent (and config-independent) packages containing firmware. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
