As per IFC binding, Absence of "little-endian" field causes registers
access in big-endian mode.
So no need to set explicit big-endian field IFC node for LS1043A and
LS1046A.

NOR and IFC controller connectivity is big-endian.
So add big-endian field in nor device tree node allowing
IFC controller to read/write data from/to the flash correctly.

Yes, this line is unrelated to this change.

Freeescale has been acquired by NXP in 2016. 
We want to add NXP copyright wherever freescale's copyright is present. But it is not possible in one-go.

So we are adding NXP copyright as and when any file having freescale's copyright  being touched.
