Fix bug in novatek-nt35560 driver's nt35560_set_brightness() which causes the driver to incorrectly report that it "failed to disable display backlight".
Add mipi_dsi_dcs_read_multi() to drm_mipi_dsi.c for improved error handling in drivers which use mipi_dsi_dcs_read() multiple times in a row. It seems like although this feature may be useful for the nt35560, we don't expect many drivers to use it. Once again, I am happy to remove this change if it's not worth maintaining. Add mipi_dsi_dcs_write_var_seq_multi() and mipi_dsi_generic_write_var_seq_multi() to drm_mipi_dsi.h to allow drivers to more conveniently construct MIPI payloads at runtime. Clean up novatek-nt35560 driver to use "multi" variants of MIPI functions which promote cleaner code.
