The current driver only uses the first context, but we need to support all of them to implement multi-stream support. Add a csi2_ctx field to cal_ctx, which indicates which of the 8 CSI2 contexts is used for the particular cal_ctx. Also clean up the context register macros to take the CSI2 context number as a parameter. Note that before this patch the CSI2 context used for both PHYs was always 0. This patch always uses cal_ctx index number as the CSI2 context. There is no functional difference, but this approach will work also in the future when we use more than 1 CSI2 context per PHY.

Setting the DMA mode bitfield in CAL_WR_DMA_CTRL supposedly enables the DMA. However, the driver currently a) continues configuring the DMA after setting the mode, and b) enables the DMA interrupts only after setting the mode. This probably doesn't cause any issues as there should be no data coming in to the DMA yet, but it's still better to fix this. Add a new function, cal_ctx_wr_dma_enable(), to set the DMA mode field, and call that function only after the DMA config and the irq enabling has been done.

This works fine for legacy mode, but is not correct for MC mode, and the list is not even used in MC mode. Fix this by adding a new function, cal_ctx_v4l2_init_mc_format, which only initializes ctx->v_fmt and ctx->fmtinfo to a default value.

So fix these, by introducing cal_ctx_destroy(), and using that in appropriate places instead of calling cal_ctx_v4l2_cleanup() in cal_media_clean(). Also use normal kzalloc (and kfree) instead of devm version as we anyway do manual cleanup for each context.
