Update the driver to use the non-deprecated mipi_dsi_*_multi() helpers, as recommended in Documentation/gpu/todo.rst. The multi variants provide proper error accumulation and handle the required DCS NOP insertions, which suits the OTM8009A command sequences. Refactor otm8009a_dcs_write_buf() and the dcs_write_seq/dcs_write_cmd_at macros to take a mipi_dsi_multi_context pointer, passing it through from callers. This ensures consistent error handling throughout the driver. Replace all mdelay() and msleep() calls within DSI command sequences with mipi_dsi_msleep() for proper error accumulation. The init, disable, and backlight update paths now return dsi_ctx.accum_err, ensuring errors are propagated to callers.
