Bug description:
[ SRU Justification ]
[ Impact ]
No machine specific ISH fw to be loaded:
```
$ sudo dmesg | grep ish
kernel: intel_ish_ipc 0000:00:12.0: ISH loader: load firmware:
intel/ish/ish_lnlm.bin
kernel: intel_ish_ipc 0000:00:12.0: ISH loader: cmd 2 failed 10
kernel: intel_ish_ipc 0000:00:12.0: ISH loader: cmd 2 failed 10
kernel: intel_ish_ipc 0000:00:12.0: ISH loader: wait response of cmd 0 timeout
```
Proposed fix
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-
firmware.git/commit/?id=96ed5b3686d0836c33c7141f6deb2c3e555aa5a8 under
upstream tag 20251011.
[ Test Plan ]
1. Install linux-firmware from -proposed pocket.
```
$ sudo apt install --no-install-recommends --yes linux-firmware
```
2. Make sure you update initramfs. The generic ish fw might have been
included in initramfs, and that will become the first choice while searching
for ish fw:
```
$ sudo update-initramfs -u -k all
```
3. Reboot and check dmesg:
```
$ sudo dmesg | grep ish
intel_ish_ipc 0000:00:12.0: ISH loader: load firmware:
intel/ish/ish_lnlm_39ceeaf8.bin
intel_ish_ipc 0000:00:12.0: ISH loader: firmware loaded. size:854528
