powerpc/fsl: set fsl,i2c-erratum-a004447 flag for P1010 i2c controllers
[ Upstream commit 19ae697a1e4edf1d755b413e3aa38da65e2db23b ]
The i2c controllers on the P1010 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 P1010 Chip Errata Rev L.
