After recent i2c rototill, a CUBIETRUCK when booting a SUNXI kernel
fails with an (nearly) endless stream of:

sunxitwi2: autoconfiguration error: unexpected status 0x20: expect 0x18
sunxitwi2: autoconfiguration error: unexpected status 0x20: expect 0x18
sunxitwi2: autoconfiguration error: unexpected status 0x20: expect 0x18


>How-To-Repeat:
Just boot SUNXI on a cubietruck.

>Fix:
