powerpc/fsl: set fsl,i2c-erratum-a004447 flag for P2041 i2c controllers 



The i2c controllers on the P2040/P2041 have an erratum where the
documented scheme for i2c bus recovery will not work (A-004447). A
different mechanism is needed which is documented in the P2040 Chip
Errata Rev Q (latest available at the time of writing).
