drm: Separate EDID Header Check from EDID Block Check
Provides function drm_edid_header_is_valid() for EDID header check
and replaces EDID header check part of function drm_edid_block_valid()
by a call of drm_edid_header_is_valid().
This is a prerequisite to extend DDC probing, e. g. in function
radeon_ddc_probe() for Radeon devices, by a central EDID header check.
Tested for kernel 2.6.35, 2.6.38 and 3.0
