package/linux-firmware: add missing hash for LICENSE.mali_cssfw

Commit
94d4ab11fea1b964991ba64e3b2964de467ec9fc ("package/linux-firmware: add
option to install ARM Mali CSF firmwares") added support for
installing the Mali CSF firmware files, but forgot to add the hash of
the license file used by those firmware files. This commit fixes this.
