As this platform data is same across most of these boards, I'd suggest we
keep a common/default platform_data in

arch/arm/plat-mxc/devices/platform-imx-ahci.c

And pass NULL in these board files, making use of the above default one.
For those boards with exceptions (e.g. special operations like GPIO to
enable/disable something at init/exit), one can still have platform data
and pass the pointer.
