Just realised that spc.c now has OPP functionality too. As the comment above
says this can be fine grained later, but just wanted to mention here. IMO we can
restrict notrace to just below functions in spc.c

ve_spc_cpu_in_wfi
ve_spc_cpu_wakeup_irq
ve_spc_global_wakeup_irq
ve_spc_powerdown
ve_spc_set_resume_addr
