The first commit adds it to the existing "Milk-V Jupiter (K1)" board. The two following commits add a "Milk-V Jupiter (M1)" board, by moving the common part, i.e. everything but the model name and the operating point tables, in a shared DTSI file. This file is then included for both K1 and M1 variants. CPU frequency scaling was verified up to 1.8 GHz on the M1 board.
