[Dali] Raven 2 detection Patch

Dali is a raven2 based asic that drives at a lower (6W) TDP than other raven 2 chips. Currently the fused internal id is the same on all raven 2 boards, this means that the detection process must be done through PCIE REV ID.

Unfortunately PCIE REV ID is not defined inside the scope of display. I created a patch to alter the fused value for internal rev_id if the chip is detected as dali through PCIE REV ID. So that detection of the chip will be possible inside of Display core.

Can you kindly provide feedback on this workaround.

Best Regards,

Aly Tawfik
