riscv: dts: spacemit: k1-milkv-jupiter: fix maximum CPU core voltage

On the Milk-V Jupiter board, the buck1 and buck2 voltage regulators,
which supply the CPU core voltage, are configured with a maximum output
voltage of 3.45V, while the highest operating point requires only
1.050V. This means that a kernel bug, OPP misconfiguration, or
privileged userspace could request a voltage above the safe operating
limit, causing possible permanent CPU damage.

Set the maximum regulator voltage to 1.050V instead.
