Log Message:
Add support for the optional dynamic minimum (in terms of MHz) via _PDL.
Comparable to T-states, this gives effectively a window of available
performance states for passive cooling. An example:
Init: max = 0, min = Pn.
Time j. Time j + 1.
----------- -----------
2000 MHz P0 max P0
P1 P1 max
P2 ==> P2
P3 P3 min
P4 P4
P5 min P5
500 Mhz Pn Pn
----------- -----------
Search: repeat (i = P0; i <= P5) repeat (i = P1; i <= P3)
