Milk-V Duo S RISC-V and ARM switching

The large core of DuoS can choose to use RISC-V or ARM processor, which can be set through the switch on the board. If you find that DuoS cannot start normally during use, please first check whether the switch is consistent with the firmware used.

If the debug serial port is connected, you can see in the first line of the boot log that starting with C means starting from the RISC-V core, and starting with B means starting from the ARM core.
