[PATCH 1/2] dt-bindings: net: qcom,bam-dmux: Add qcom,shikra-bam-dmux compatible

[Vishnu Santhosh]

On platforms where the modem DMAs into the BAM-DMUX RX data buffers and
the XPU enforces per-region access control, each individually
DMA-mapped RX buffer consumes an XPU resource group. With only ~16
groups available, the per-buffer mappings exhaust the table and inbound
transfers fault.

Add qcom,shikra-bam-dmux as an additional compatible for the Shikra SoC,
paired with the generic qcom,bam-dmux fallback, so the driver can match
on it via its of_device_id table.
