accel/qaic: Add datapath

Browse Source

Add the datapath component that manages BOs and submits them to running
workloads on the qaic device via the dma_bridge hardware. This allows
QAIC clients to interact with their workloads (run inferences) via the
following ioctls along with mmap():

DRM_IOCTL_QAIC_CREATE_BO
DRM_IOCTL_QAIC_MMAP_BO
DRM_IOCTL_QAIC_ATTACH_SLICE_BO
DRM_IOCTL_QAIC_EXECUTE_BO
DRM_IOCTL_QAIC_PARTIAL_EXECUTE_BO
DRM_IOCTL_QAIC_WAIT_BO
DRM_IOCTL_QAIC_PERF_STATS_BO
