arm64: dts: qcom: sdm845: add SLPI FastRPC support
Qualcomm SDM845 SoC features a SLPI DSP which uses FastRPC through
an allocated memory region to load files from the host filesystem
such as sensor configuration files.
Add a FastRPC node at /dev/fastrpc-sdsp and a DMA region, similar to
downstream, to allow userspace to communicate with the SLPI via the
FastRPC interface for initializing the sensors on the SLPI.
