hw/i2c-ddc: Do not fail writes
The tx function of the DDC I2C slave emulation was returning 1
on all writes resulting in NACK in the I2C bus. Changing it to
0 makes the DDC I2C work fine with bit-banged I2C such as the
versatile I2C.
I guess it was not affecting whatever I2C controller this was
used with until now, but with the Versatile I2C it surely
does not work.
