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

[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.
