tools/power/x86/intel-speed-select: Fix display of uncore min frequency

Browse source 
Uncore P1 is not uncore minmum frequency. This is uncore base frequency.
Correct display from uncore-frequency-min(MHz)
to uncore-frequency-base(Mhz).

To get uncore min frequency use mailbox command
CONFIG_TDP_GET_RATIO_INFO. Use this mailbox to get uncore frequency
limits when present.
