Add a new Qualcomm JPEG V4L2 mem2mem encoder driver for Qualcomm SoCs.

The driver provides hardware-accelerated JPEG encoding through the V4L2
mem2mem framework.

Currently supported platforms are:
- sc7180
- sm8250
- sm7325
- sc7280
- qcm6490
- sm8550

The driver has been functionally verified only on qcm6490 hardware at
this time. Support for the remaining platforms is based on matching
hardware compatibility and available platform integration data.

Main features:
- V4L2 mem2mem encoder interface
- Hardware JPEG encoding
- DMA-based buffer handling
- Device-tree based platform integration
- Runtime PM support

Testing performed on qcm6490:
- JPEG encoding
- Multiple image resolutions
- Repeated streaming start/stop
- Long-running encode stability tests
- GStreamer pipeline validation

Known limitations:
- Image scaling is currently not supported
- Image width and height must be aligned to 16 pixels
- Other listed platforms are compile-tested only

This series includes:
- DT bindings for Qualcomm JPEG encoder hardware
- core JPEG encoder driver implementation
- V4L2 mem2mem integration
- platform support for supported Qualcomm SoCs
- runtime PM integration
