The driver do support I2C_M_IGNORE_NAK, so add
I2C_FUNC_PROTOCOL_MANGLING to the feature list.

The driver do support I2C_M_IGNORE_NAK, so the
I2C_FUNC_PROTOCOL_MANGLING bit should be set.

I2C_M_IGNORE_NAK is the only supported "mangling-feature" though, but
other i2c bus drivers also seems to support only a subset of available
mangling-features, so I guess this is ok.
