powernow-k8: Fix indexing issue
commit a8eb28480e9b637cc78b9aa5e08612ba97e1317a upstream. The driver uses the pstate number from the status register as index in its table of ACPI pstates (powernow_table). This is wrong as this is not a 1-to-1 mapping. For example we can have _PSS information to just utilize Pstate 0 and Pstate 4, ie. powernow-k8: Core Performance Boosting: on. powernow-k8: 0 : pstate 0 (2200 MHz) powernow-k8: 1 : pstate 4 (1400 MHz) In this example the driver's powernow_table has just 2 entries. Using the pstate number (4) as index into this table is just plain wrong.
