linux-firmware: Update SRCREV, pull in iwlwifi-7260 support
Fixes [YOCTO #5110]
Add support for the iwlwifi 7260 adapters. This creates a new package
and includes support in the default linux-firmware (everything) package.
Update the iwlwifi and radeon license checksums. Extensions to the
copyright date ranges were the only change to the LICENSE files.
