ctl_gfx_controller_write_8b_sequence sends 8-bit command and parameters pointed to by seq using the write function. The size of the sequence is n bytes. The parameter delay indicates a distinguished value that, if found in the command sequence, indicates a delay, in milliseconds, taken from the parameter.
