(Un)registers an interrupt handler for the timer.
/*
* cb will be invoked whenever the timer generates an interrupt (that is, when the counter reaches the threshold set via SceSystimerForDriver_A73351C1())
* timer and pUserData arguments will be the same as provided to this function
* cb will only be called if SceSystimerForDriver_A73351C1() has been called with non-zero argument (e.g. timer has a threshold)
* cb can be NULL, in which case targetCPU will not be set
*
* targetCPU follows the same rules as sceKernelSetIntrTarget() - see SceKernelIntrMgr for more info
