misc-nonfree: Include all Arm Mali firmware

Various new Arm Mali firmware files were added in upstream commit
930ef9046e38 ("panthor: Add firmware for more Mali GPUs")

Therefore extend the defines pattern to include them all.
Also extend the copyright pattern in a similar vein as the new files are
licensed under the same license terms as the existing file.
