2b6f3804a0 edid: parse standard timings 
The edid-decode output uses data from the DMT, so we're not able
to replicate it yet.

c383417629 edid: prefix private functions with "_di_" 
The extra underscore indicates that it's not a function which is
part of our public API. This will allow the next commit to setup the
linker to export functions based on their name.

6cbaf27c91 edid: switch to a statically allocated extension array 
The spec defines an upper bound for the extension block count,
which means we don't need to dynamically allocate the array. This
simplifies our logic a bit by removing an allocation error codepath.

The array is NULL-terminated, so EDID_MAX_BLOCK_COUNT is suitable
since it's the max number of extension blocks including the base
block, and the array doesn't include the base block.

ad1e3f4167 Add very basic EDID functions 
Introduce an opaque struct di_edid to host EDID structures. Add
a function to create a di_edid (with basic size, header and
checksum validation). Add functions to fetch the EDID version and
revision.

This doesn't do much, but hopefully can be used as a fundation.
