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.

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.

The only place where the field is used is cal_camerarx_get_ext_link_freq(). With multiple streams the whole concept of single input format is not valid anymore, so lets remove the field by looking up the format in cal_camerarx_get_ext_link_freq(), making it easier to handle the multistream-case in the following patches.

Documentation/userspace-api/media/v4l/subdev-formats.rst states: "The media bus pixel codes document parallel formats. Should the pixel data be transported over a serial bus, the media bus pixel code that describes a parallel format that transfers a sample on a single clock cycle is used. For instance, both MEDIA_BUS_FMT_BGR888_1X24 and MEDIA_BUS_FMT_BGR888_3X8 are used on parallel busses for transferring an 8 bits per sample BGR data, whereas on serial busses the data in this format is only referred to using MEDIA_BUS_FMT_BGR888_1X24. This is because there is effectively only a single way to transport that format on the serial busses." Some MIPI CSI receivers strictly obey this definition and declare support for only *1X_* formats. Hence, complement the supported media bus formats with their 1X16 versions (currently applicable to yuyv, uyvy) to enhance interoperability with CSI receivers.
