For Intel SST turbo-freq feature to be enabled, the turbo mode on the
platform must be enabled also. If turbo mode is disabled, display error
while enabling turbo-freq feature.

Since this is a trivial patch, I am not sending a PULL request.

Thank you for your patch, I've applied this patch to my review-hans
branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans
Note it will show up in my review-hans branch once I've pushed my
local branch there, which might take a while.
Once I've run some tests on this branch the patches there will be
added to the platform-drivers-x86/for-next branch and eventually
will be included in the pdx86 pull-request to Linus for the next
merge-window.
Regards,
Hans

Note not related to this patch, but when test building intel-speed-select
I got the following compiler warning:
CC hfi-events.o
In function ‘process_hfi_event’,
inlined from ‘handle_event’ at hfi-events.c:220:5:
hfi-events.c:184:9: warning: ‘perf_cap.cpu’ may be used uninitialized [-Wmaybe-uninitialized]
184 | process_level_change(perf_cap->cpu);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
hfi-events.c: In function ‘handle_event’:
hfi-events.c:193:25: note: ‘perf_cap.cpu’ was declared here
193 | struct perf_cap perf_cap;
| ^~~~~~~~

Let me send a patch to fix. In reality this will not happen as HFI
message will always have a CPU.
