feat(versal): add SMCCC call TF_A_PM_REGISTER_SGI

Browse source 
This call is used to register and reset SGI interrupt.
Before this functionality was performed using IOCTL_REGISTER_SGI
pm_ioctl EEMI call. It's not correct use of PM_IOCTL as it is
not EEMI functionality. Instead this new SMCCC call will be
handled by TF-A specific handler.
