[SRU][N:linux-azure-nvidia][PATCH 0/1] Include cppc_cpufreq in linux-modules

[ioanna-maria.alifieraki at canonical.com]

From: Ioanna Alifieraki <ioanna-maria.alifieraki at canonical.com>

[Impact]
Include cppc_cpufreq module in linux-modules package instead of
linux-modules-extra so that cpufreq is enabled by default (without
the need to install linux-modules-extra).

The fix is fairly simple, add the cppc_cpufreq.ko modules to 
azure-nvidia.inclusion-list.

[Test Case]

Currently cppc_cpufreq is not included in linux-modules package.

root at flavio:/home/ubuntu# uname -rv
6.8.0-1019-azure-nvidia #20-Ubuntu SMP Fri Jun 27 23:52:00 UTC 2025
root at flavio:/home/ubuntu# lsmod | grep cpufreq
root at flavio:/home/ubuntu#
root at flavio:/home/ubuntu# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
cat: /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor: No such file or directory

Preparing a test kernel with the fix and installing only the linux-image
and linux-modules package, cppc_cpufreq is present.

ubuntu at flavio:~$ uname -rv
6.8.0-1020-azure-nvidia #21 SMP Mon Aug 4 16:37:34 UTC 2025

root at flavio:/home/ubuntu# lsmod | grep cpufreq
cppc_cpufreq 262144 0
root at flavio:/home/ubuntu# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

[Where problems could occur]

The fix just adds a module in linux-modules package. Not any severe
regressions expected. However, those who expected to find this module
in modules-extra will not find there anymore.

[Other]

The fix is needed for linux-azure-nvidia, for Noble, 6.8.
