Subject: [PATCH] ARM: dts: qcom: msm8974-honami: Set DMA as remotely controlled

This patch adds the qcom,controlled-remotely property for the blsp2_bam
controller node.  This board requires this, otherwise the board fails to
boot due to access of protected registers during BAM initialization.

Fixes: 62bc81792223 dts: msm8974: Add blsp2_bam dma node
