[PATCH v3 5/6] riscv: dts: spacemit: Add K3 I2C6 pinctrl state

[Troy Mitchell]

Add the K3 I2C6 pinctrl state used by boards that route I2C6 to pads 7
and 8. Use a 25 mA drive strength, which is supported for both K3 IO
voltage domains, and leave board-specific IO voltage selection to board
files.
