commit e4731baaf29438508197d3a8a6d4f5a8c51663f8 upstream.
The nominal frequency in cpudata is maintained in MHz whereas all other
frequencies are in KHz. This means we have to convert nominal frequency
value to KHz before we do any interaction with other frequency values.
In amd_pstate_set_boost(), this conversion from MHz to KHz is missed,
fix that.
Tested on a AMD Zen4 EPYC server
