Add EyeQ6H support to the nmk-i2c AMBA driver. It shares the same quirk as EyeQ5: the memory bus only supports 32-bit accesses. Avoid writeb() and readb() by reusing the same `priv->has_32b_bus` flag. It does NOT need to write speed-mode specific value into a register; therefore it does not depend on the mobileye,olb DT property.
