Subject: [PATCH 1/2] intel-speed-select: Display turbo-ratio-limits as a table
The output of the Turbo Ratio Limits is 75 lines long (each bucket has
3 lines and the headers). This can be shrunk down into a table that is
easier to consume for both scripts and humans.
Display Turbo Ratio Limits in a table.
