[igt-dev] [PATCH i-g-t 3/3] tools/intel_vbt_decode: Dump the GPIO value/config/flag as a raw hex byte

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

The spec is totally confused when it comes to the GPIO flags byte.
To allow us to inspect that the decoded result at least seems
sensible let's also dump the raw byte. Should at least show if
some bits are set which we're not expecting.
