[PATCH 01/17] DRM/KMS/EDID: Mask out Segment Bits when calculating Offset.

[Egbert Eich]

This patch is a bit cosmetic as the variable size will truncate
the start address anyway but for readability it should be made
explicite that the lowest bit in the EDID block number determines
the I2C start address.
