[Bug 2071698] Re: Integrated Sensor Hub (ISH) support for Intel Lunar Lake platform

This bug is awaiting verification that the linux-
hwe-6.11/6.11.0-9.9~24.04.1 kernel in -proposed solves the problem.
Please test the kernel and update this bug with the results. If the
problem is solved, change the tag 'verification-needed-noble-linux-
hwe-6.11' to 'verification-done-noble-linux-hwe-6.11'. If the problem
still exists, change the tag 'verification-needed-noble-linux-hwe-6.11'
to 'verification-failed-noble-linux-hwe-6.11'.


If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.


See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Bug description:
[SRU Justification]

[Impact]

Starting from Intel Lunar Lake, the ISH firmware will reside in system
root as separated blobs, and the kernel driver is responsible for
loading a preferred one based on DMI info.

[Fix]

Kernel fixes in linux-next:
* aa4674c525e1e hid: intel-ish-hid: Add support for vendor customized firmware loading
* 641361538b68d HID: intel-ish-hid: Use CPU generation string in driver_data
* 87de1615194ee Documentation: hid: intel-ish-hid: Add vendor custom firmware loading

linux-firmware in upstream tag 20240709:
* 33a8b2a7f604 linux-firmware: Add ISH firmware file for Intel Lunar Lake platform

[Test Case]

dmesg dumps:
```
intel_ish_ipc 0000:00:12.0: ISH loader: firmware loaded. size:748032
ish-hid {33AECD58-B679-4E54-9BD9-A04D34F0C226}: [hid-ish]: enum_devices_done OK, num_hid_devices=2

```

[Where problems could occur]

This is to include generic blob provided by Intel for all Lunar Lake
platforms. It may not be stable, may not be functional, and may have
various problems until the hardware vendor submit their own.
