msm_fb: hdmi: Fix for EDID parser error.

For an older TV, which doesn't contain Data Block Collection,
the EDID parser was parsing wrong supported video resolutions.
As per EDID standard, if EDID block 1 byte 2 is 0x04, it means
there is no DBC available in EDID so the supported video resolutions
should be read from DTDs of block0 and block1 instead of SVD of
DBC. Reading DTDs for supported video resolutions instead of DBC for
byte 2 being 0x04 case, fixed the issue.
