Adapt license array to use SPDX license identifiers
Description:
Currently we use legacy license identifiers in the license array of the PKGBUILD. However, many different licenses apply to the files in the packages provided by this PKGBUILD.
We need to assess each license file in https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/ and figure out the correct license identifiers for them. Afterwards we need to add the license files only to their respective targets and update the license arrays for all split packages.
