radv/ci: bump most jobs to the kernel to 6.1 + latest firmwares

radv/ci: bump most jobs to the kernel to 6.1 + latest firmwares

Unfortunately, not all jobs can be using Linux 6.1 right now, as
NAVI10 hits __vm_enough_memory errors then hangs in VKCTS. So for
this job, we will keep Linux 5.17 until this gets fixed.
