soc/amd: introduce and use PSTATE_MSR macro
Instead of adding the P-state number to the PSTATE_0_MSR number to get the P-state MSR number for the rdmsr call, provide a macro that directly calculates the MSR number for a given power state. Also drop the unused PSTATE_[1..4]_MSR definitions which also didn't cover all P-state MSRs available in the hardware.
