There are two ways to define  I2C_xxxx macros:
gpio or direct SoC access

if you are using gpio to define macros, I think you get this warnings.

If you are using direct SoC access (no gpio driver needed)
there are no warnings 
e.g.

#define I2C_ACTIVE	writel(AT91_PMX_AA_TWD, &pio->pioa.mddr);
#define I2C_TRISTATE	writel(AT91_PMX_AA_TWD, &pio->pioa.mder);
and so on

We need some volunteers, which convert the drivers.
