drm/edid: Fix parsing of EDID 1.4 Established Timings III descriptor

Browse source 
The EDID 1.4 specification section 3.10.3.9 defines an Established Timings III
descriptor (tag #F7h). The parsing of this descriptor by drm_est3_modes() is
off by one byte: the offset of the first timing bitmap is 6, not 5.
