[PATCH 09/12] drm/edid: convert extension block read to EDID block read helper

[Jani Nikula]

Use the EDID block read helper also for extension block reads, making
edid_block_read() the only place with the read retry logic.

Note: We observe that drm_do_get_edid() does not use invalid extension
blocks to flag the EDID as corrupt.
