drm/msm/a6xx: Allow IFPC with perfcntr stream
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.
