Subject: [PATCH] arm64: dts: msm: Enable cb handing in irq context

GLINK changed their default handling of channel callbacks from the irq
context to a callback thread. This change impacted FastRPC performance.

Configure FastRPC to use irq context to handle channel callbacks to fix
the performance regression.
