[PATCH 6.1 177/197] arm64: dts: qcom: msm8916: Enable blsp_dma by default

[ Upstream commit 0154d3594af3c198532ac7b4ab70f50fb5207a15 ]

Adding the "dmas" to the I2C controllers prevents probing them if
blsp_dma is disabled (infinite probe deferral). Avoid this by enabling
blsp_dma by default - it's an integral part of the SoC that is almost
always used (even if just for UART).
