Hi,
I noticed that these firmware files were missing inside the initrd when
including the brcmfmac kernel module:
```
/usr/lib/firmware/brcm/brcmfmac43436-sdio.clm_blob.zst
/usr/lib/firmware/brcm/brcmfmac43456-sdio.clm_blob.zst
/usr/lib/firmware/brcm/brcmfmac43430-sdio.raspberrypi,3-model-b.clm_blob.zst
/usr/lib/firmware/brcm/brcmfmac43430b0-sdio.raspberrypi,model-zero-2-w.clm_blob.zst
/usr/lib/firmware/brcm/brcmfmac43436-sdio.raspberrypi,model-zero-2-w.clm_blob.zst
/usr/lib/firmware/brcm/brcmfmac43455-sdio.raspberrypi,3-model-a-plus.clm_blob.zst
/usr/lib/firmware/brcm/brcmfmac43455-sdio.raspberrypi,3-model-b-plus.clm_blob.zst
/usr/lib/firmware/brcm/brcmfmac43455-sdio.raspberrypi,4-compute-module.clm_blob.zst
/usr/lib/firmware/brcm/brcmfmac43455-sdio.raspberrypi,4-model-b.clm_blob.zst
/usr/lib/firmware/brcm/brcmfmac43455-sdio.raspberrypi,5-compute-module.clm_blob.zst
/usr/lib/firmware/brcm/brcmfmac43455-sdio.raspberrypi,5-model-b.clm_blob.zst
/usr/lib/firmware/brcm/brcmfmac43455-sdio.raspberrypi,500.clm_blob.zst
/usr/lib/firmware/brcm/brcmfmac43456-sdio.raspberrypi,4-compute-module.clm_blob.zst
/usr/lib/firmware/brcm/brcmfmac43456-sdio.raspberrypi,400.clm_blob.zst
```
These changes should be backported to the stable kernel releases as
well.

On Ubuntu 26.10 these firmware file are missing inside the initrd when
including the brcmfmac kernel module:
```
/usr/lib/firmware/brcm/brcmfmac43430-sdio.raspberrypi,3-model-b.clm_blob.zst

/usr/lib/firmware/brcm/brcmfmac43456-sdio.raspberrypi,400.clm_blob.zst
```
Commit 885f256f61f9 ("brcmfmac: Add clm_blob firmware files to modinfo")
added clm_blob firmware binaries, but did not add them for per-board
firmware binaries. So add a similar glob for the per-board firmware
binaries.

So include the clm_blob firmware file for brcmfmac43456-sdio similar to
the other firmware files.
