I have tried to merge them. I kept common hdmi_tg_regs
for v13 and v14 (v14 TG regs are extension to v13 TG regs).
But hdmi_core_regs fields are one to one mapped with Hdmi
Core Register which are bit different in both the versions.
Additionally, using common hdmi_conf_regs which have unions
for each hw version. A new version can be seamlessly added
to the list.
Please tell me specific region for improvements.

Rahul Sharma.
