media: raspberrypi: cfe: Fix mapping of dmabuf buffers
When using buffers from DRM, DMA-API gives a warning about: "mapping sg
segment longer than device claims to support [len=307200] [max=65536]"
Add a call to vb2_dma_contig_set_max_seg_size() to tell the DMA-API
about the supported segment size (which is UINT_MAX).
Fixes: 6edb685abb2a ("media: raspberrypi: Add support for RP1-CFE")
