CMD_LOGO - play FTDI logo animation
The logo command causes the co-processor engine to play back a short animation of the
FTDI logo. During logo playback the MCU should not access any FT800 resources. After
2.5 seconds have elapsed, the co-processor engine writes zero to REG_CMD_READ and
REG_CMD_WRITE, and starts waiting for commands. After this command is complete,
the MCU shall write the next command to the starting address of RAM_CMD.
