[PATCH v5 1/4] dt-bindings: misc: qcom,fastrpc: Add compatible for Kaanapali

[Kumari Pallavi]

Kaanapali introduces changes in DSP IOVA layout and CDSP DMA addressing
that differ from previous SoCs. The SID field moves within the physical
address, and CDSP now supports a wider DMA range, requiring updated
sid_pos and DMA mask handling in the driver.
To apply these changes only on Kaanapali, add a SoC-specific compatible
string "qcom,kaanapali-fastrpc". Older DTs using "qcom,fastrpc" remain
valid.
