PSCI: Resolve GCC static analysis false positive

When BL31 is compiled at `-O3` optimization level using Linaro GCC 4.9
AArch64 toolchain, it reports the following error:

```
services/std_svc/psci/psci_common.c: In function 'psci_do_state_coordination':
services/std_svc/psci/psci_common.c:220:27: error: array subscript is above
array bounds [-Werror=array-bounds]
  psci_req_local_pwr_states[pwrlvl - 1][cpu_idx] = req_pwr_state;
                           ^
```

This error is a false positive and this patch resolves the error by asserting
the array bounds in `psci_do_state_coordination()`.

Fixes ARM-software/tf-issues#347
