drm/amdgpu: Include sdma_4_4_4.bin

The dracut initramfs generator relies on the kernel module to identify
any firmware .bin files that it might require. A kernel module can do
this using the MODULE_FIRMWARE macro. This change backports the upstream
commit that declares the firmware sdma_4_4_4.bin, which is needed to
boot a machine with an AMD GPU MI350/MI355 that has the SDMA 4.4.4 IP.
