Add the compatible string for 14nm DSI PHY (used in MSM8996/APQ8096).
From 14nm PHY onwards, the "dsi_phy_regulator" reg-name is not required,
but "dsi_phy_lane" reg-name is. Update the doc to specify the reg-names
each PHY revision needs.

Did you mean to add this?
Yes, I didn't intend it to be a part of this patch, but this supply is indeed needed for the
20nm PHY. I'll move this to a separate patch.
Thanks,
