drm/msm/a6xx: Allow IFPC with perfcntr stream

Browse source

Now that the dynamic pwrup reglist has SEL reg values to restore
appended, so that SEL regs are restored on IFPC exit, we can stop
completely disabling IFPC while global counter sampling is active.

To accomplish this, we re-use sysprof_setup() with a force_on param
to inhibit IFPC specifically while the counter regs are being read,
while leaving IFPC enabled the rest of the time.
