tools/power/x86/intel-speed-select: Change TRL display for Emerald Rapids

Emerald Rapids doesn't specify TRL (Turbo Ratio Limits) based instruction
types. Instead it specifies 5 TRL levels, which can be anyone of the
instruction types.

Increase TRL levels to 5 for Emerald Rapids. Also change display to show
by level number. Show only non zero level values.
