[RFC] perf pmu-events: Fix typo in idle-cycles-frontend description

[RFC] perf pmu-events: Fix typo in idle-cycles-frontend description

[Pu Hu]

From: Pu Hu <hupu@transsion.com>

The brief description of the idle-cycles-frontend legacy hardware event
refers to its alias as "stalled-cycles-fronted", but there is no such
event. The correct event name is "stalled-cycles-frontend".

This typo is visible in the output of "perf list", for example:

  idle-cycles-frontend
       [Stalled cycles during issue [This event is an alias of
        stalled-cycles-fronted]. Unit: armv8_pmuv3]

Fix the spelling so that the description points to the valid event name.

Hi maintainers,

Just to add some context, I reproduced this issue on an arm64 platform.

Without this patch, "perf list" reports:

   idle-cycles-frontend
        [Stalled cycles during issue [This event is an alias of
         stalled-cycles-fronted]. Unit: armv8_pmuv3]

But there is no "stalled-cycles-fronted" event. The intended event name 
is "stalled-cycles-frontend".

After the fix, the description points to the correct event name.

Thanks,
Pu Hu

Applied to perf-tools-next, thanks!
