psci: fix values of incorrectly defined constants
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.
