[Impact]
perf/uncore is not supported on Oracular and OEM-6.11 kernel.

[Fix]
Add LNL and ARL support, the commits are just landed in upstream.

[Test]
Tested on hardware, the sysfs show:
On ARL:
$ cat /sys/devices/uncore_*/type
30
31
16
26
27
17
18
19

21

23
24
25
34
28
29
32
33
36
37

On LNL:
$ cat /sys/devices/uncore_*/type
21
22
17
18
19
20
25
26
23
24
28

[Where problems could occur]
It may break uncore support on LNL and ARL.
