cpufreq: powernv: Dont assume distinct pstate values for nominal and pmin
commit 3fa4680b860bf48b437d6a2c039789c4abe202ae upstream.
Some OpenPOWER boxes can have same pstate values for nominal and
pmin pstates. In these boxes the current code will not initialize
'powernv_pstate_info.min' variable and result in erroneous CPU
frequency reporting. This patch fixes this problem.
Fixes: 09ca4c9b5958 (cpufreq: powernv: Replacing pstate_id with frequency table index)
