The generated EDIDs were wrongly indicating that they support analog sync.
Fixup the detailed timings flags to advertise digital sync instead.
Currently the Linux kernel seems to ignore this completely. However I'd prefer
to fix this anyway to make sure we don't run into issues if an EDID consumer
actually cares about it.
The header definitions for EDID_PT_* values has been re-organized to make it
clearer in which situations the flags are relevant.
Changes from v1 to v2:
- Fix misleading commit message
- Revert the "misc" → "features" rename
- Re-organize EDID_PT_* definitions to make them clearer
Changes from v2 to v3:
- Include review changelog in commit message
- Fix "Fixes:" tag to conform to the kernel style
- Re-order EDID_PT_* definitions to sort by descending bitshift

For the purposes of testing different EDID features, we need to generate more
and more complex EDID blobs (e.g. with audio support). However currently IGT
uses a macro-based system to generate EDIDs. This doesn't scale well and is
pretty inflexible.
This commit introduces a new little library to generate EDIDs. For now it can't
do more than the old macro. Future commits will extend the API.
The structures are mostly based on the Linux kernel code (drm_edid.h). Setters
have been added for convenience.

This has been replaced by igt_kms_get_base_edid().

Add a function to set an EDID data block on a connector and include a
set of generic EDID blocks for testing.
