Revert: "dt-bindings: add documentation for sde-limit"

Browse source 
This reverts commit 658f1491b962fceccb622a9ba78e74af3c1fc0f0
from msm-4.19 which was ported as part of the display device
tree techpack.

Support for sde-limits has been removed from the driver as it's
no longer needed. BW limits have moved to per target based XML
files in user-space and linewidth limits already have other
properties for specifying.

- qcom,sde-limits: A node that lists the limits for different properties. This node
can have multiple child nodes. Each child node represents a
specific usecase limit. The usecase can be defined for properties like
sspp linewidth, bw limit etc.
e.g. qcom,sde-limits
-- qcom,sde-limit-name: name of the usecase
-- qcom,sde-limit-cases: different usecases to be considered
-- qcom,sde-limit-ids: respective ids for the above usecases
-- qcom,sde-limit-values: usecase and value for different combinations
