[PATCH 2/9] dt-bindings: msm/dp: bring back support for legacy DP reg property

[Dmitry Baryshkov]

The commit 687825c402f1 ("dt-bindings: msm/dp: Change reg definition")
changed reg property to list separate register blocks, which broke
validation of DT files using single register block. Restore
compatibility with older (single register block) DT files by declaring
it as a deprecated alternative.
