media: ti-vpe: cal: Fold PPI enable in CAMERARX .s_stream()

Browse source

To further decouple the context and CAMERARX components, move the call
to cal_camerarx_ppi_enable() from cal_start_streaming() to the CAMERARX
.s_stream() operation. The DMA destination address has to be set before
starting the CAMERARX, which is desirable anyway.

cal_camerarx_ppi_disable() will be addressed separately.
