drm/radeon/kms: add connectors even if i2c fails

Sometimes the i2c test in i2c_bit_add_bus fails if this happens we fail to register the i2c adapter and eventually fail to add the connector. If i2c fails, add the connector to the user can at least force it on. Note that some distros set i2c-algo-bit.bit_test to 1 by default which sometimes fails preventing the ddc i2c adapter from being added. The i2c adapter works even if the bit test fails, probably due to pre/post_xfer not getting called in the test_bit function. I have another patch to follow up on that.
