240526-01 - experimental tiny alpine image for the milk v duo 64mb riscv64 sbc

• this is just an experimental testing image
• see: https://github.com/hexdump0815/imagebuilder/tree/main/systems/milk_v_duo
• based on alpine edge riscv64
• the v5.10.4 milk-v legacy kernel is used
• no display or gpu support as the kernel does not easily support any display hardware and the devices do not have a gpu
• it is intended only for running the system from an sd card
• username/password is as usual linux/changeme
