From: André Apitzsch <git@apitzsch.eu>
The blsp_dma controller is shared between the different subsystems,
which is why it is already initialized by the firmware. We should not
reinitialize it from Linux to avoid potential other users of the DMA
engine to misbehave.
In mainline this can be described using the "qcom,controlled-remotely"
property. In the downstream/vendor kernel from Qualcomm there is an
opposite "qcom,managed-locally" property. This property is *not* set
for the qcom,sps-dma@7884000 and qcom,sps-dma@7ac4000 [1] so adding
"qcom,controlled-remotely" upstream matches the behavior of the
downstream/vendor kernel.
Adding this fixes booting Longcheer L9360.
