From: Thara Gopinath <redacted> On certain Snapdragon processors, the crypto engine clocks are enabled by default by security firmware and the driver need not/ should not handle the clocks. Make acquiring of all the clocks optional in crypto enginer driver so that the driver intializes properly even if no clocks are specified in the dt.
