Unify type of "cpu_idx" across PSCI module.

Browse source 
cpu_idx is used as mix of `unsigned int` and `signed int` in code
with typecasting at some places. This change is to unify the
cpu_idx as `unsigned int` as underlying API;s `plat_my_core_pos`
returns `unsigned int`

It was discovered via coverity issue CID 354715
