i2c: nomadik: support Mobileye EyeQ6H I2C controller
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.
