Pass non-secure context to psci functions. When cpu/system suspends,
cpu may loose power, so when back to linux from tee, tee
needs to return to a linux resume point, not the usual return address
after "smc" instruction. So we need to modify the mon_lr
value in non-secure context.
Psci runs in monitor mode, sm_get_nsec_ctx can not be used,
so pass the non-secure context pointer to the psci suspend function.
