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.
