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.

Add new UABI and implementation of PERFCNTR_CONFIG ioctl.
A bit more work is required to configure the pwrup_reglist for the GMU
to restore SELect regs on exit of IFPC, before we can stop disabling
IFPC while global counter collection. This will follow in a later
commit, but will be transparent to userspace.
