msm: mdss: edid: modify the extended data block's length check
EDID parser is validating the minimum length of Extended data blocks
before parsing them. Current minimum length is 2 bytes but some
extended data block like Y420CMDB's length can be 1 data byte.
Modify the minimum length to 1 data byte.
