The series addresses the kernel warnings reported by Johan at [1] and are
are required to X1E cpufreq device tree changes [2] to land.

The following warnings remain unadressed:

^^ exist because SCP reports duplicate values for the highest sustainable
freq for perf domains 1 and 2. These are the only freqs that appear as
duplicates and will be fixed with a firmware update. FWIW the warnings
that we are addressing in this series will also get fixed by a firmware
update but they still have to land for devices already out in the wild.

V2:
* Include the fix for do_xfer timeout
* Include the fix debugfs node creation failure
* Include Cristian's fix for skipping opp duplication

V1:
* add missing MSG_SUPPORTS_FASTCHANNEL definition.

Base branch: next-20241004
