f24644581b tools/arch/x86/intel_sdsi: Add current meter support 
Add support to read the 'meter_current' file. The display is the same as
the 'meter_certificate', but will show the current snapshot of the
counters.

09d70ded6c tools/arch/x86/intel_sdsi: Fix meter_certificate decoding 
Fix errors in the calculation of the start position of the counters and in
the display loop. While here, use a #define for the bundle count and size.

a66f962f67 tools/arch/x86/intel_sdsi: Fix maximum meter bundle length 
The maximum number of bundles in the meter certificate was set to 8 which
is much less than the maximum. Instead, since the bundles appear at the end
of the file, set it based on the remaining file size from the bundle start
position.
