media: ti: j721e-csi2rx: separate out device and context

The TI CSI2RX wrapper has two parts: the main device and the DMA
contexts. The driver was originally written with single camera capture
in mind, so only one DMA context was needed. For the sake of simplicity,
the context specific stuff was not modeled different to the main device.

To enable multiplexed stream capture, the contexts need to be separated
out from the main device. Create a struct ti_csi2rx_ctx that holds the
DMA context specific things. Separate out functions handling the device
and context related functionality.
