drm/msm/adreno: Convert the show/crash file format

Browse Source 
Convert the format of the 'show' debugfs file and the crash
dump to a  format resembling YAML. This should be easier to
parse and be more flexible for future changes and expansions.

v2: Use a standard .rst for the msm crashdump documentation
