[PATCH v2 2/4] dt-bindings: clock: qcom: Add EVA clock and reset controller for Glymur SoC

[Taniya Das <taniya.das@oss.qualcomm.com>]

Add the device tree bindings for the enhanced video analytics(EVA) clock
controller which is required on Qualcomm Glymur SoC. The controller
provides clocks, resets and power domains for the EVA subsystem.
