i2c_prope set the dev->errata flag, but omap_i2c_init cleared the flag again. Move the errata handling to i2c_init.

  also in my opinion moving the reset to 0 should be moved to probe.
Do you mean moving all setting of the errate flag to probe instead of having it in init?

also you may want to cc linux-i2c for the driver patches.
Done.
