[PATCH v6 1/3] dt-bindings: media: qcom: Add JPEG encoder binding

Add device-tree binding for the Qualcomm JPEG encoder hardware block
present in SM8250 (Kona) SoCs.

The JPEG encoder is a standalone hardware IP within the camera subsystem
that performs JPEG compression in memory-to-memory fashion.  It is
separate from the CAMSS ISP pipeline and has its own register space,
interrupt, clocks, power domain, IOMMU streams, and interconnect paths.
