tegra_dsi_readl() can read from any of the two DSI controllers’ registers, both are supposed to be identical for ganged mode. Hence we read from INSTANCE_0.
APIs tegra_dsi_controller_writel() and tegra_dsi_controller_readl() were introduced to take care of writing/reading individual DSI controller’s registers.
