psci: fix values of incorrectly defined constants

Browse source 
This patch fixes the following constant values in the psci.h:

1. The affinity level shift value in the power_state parameter of the
   cpu_suspend psci call. The previous value was preventing shutdown
   of the affinity level 1.

2. The values used for affinity state constants (ON, OFF,
   ON_PENDING). They did not match the values expected to be returned
   by the affinity_info psci api as mentioned in the spec.

3. The state id shift value in the power_state parameter of the
   cpu_suspend psci call.
