video: dw_mipi_dsi: fix [hv]sync active vs back porch

The wrong fields are pulled out of the timings here so the values
programmed into the DSI_VID_HSA_LINES/DSI_VID_HBP_LINES and
DSI_VID_VSA_LINES/DSI_VID_VBP_LINES registers are swapped.

Use the right fields so that the correct values are programmed.
