The driver recently learned to handle platform ids.  Make use of this
new feature.  The up side is that the driver needs less knowledge about
the spi interfaces used on different SoCs.

Group soc specific data in a global struct instead of repeating it for
each call to imxXX_add_spi_imxX.  The structs holding the actual data
are placed in .init.constdata and so don't do much harm.  Compared to
the previous approach this reduces code size to call imx_add_spi_imx.

In order to make this patch compile, even if the flexcan driver with
it's header defining the platform data isn't merged yet, two ifdefs have
been added. They effect that the "imx_add_flexcan" function results in a
no-op function if the driver hasn't been activated.

These ifdefs can be removed after the flexcan driver has been merged.

Instead of having a platform device defined in a devices.c and register
it in the machine file allocate it dynamically.  This reduces the size
of needed memory as the new function is discarded after init and only
the existing devices are created.

This should be a globally available function, see

	http://thread.gmane.org/gmane.linux.kernel/998881/focus=998882

Until this hits mainline create a similar function available for imx
platforms only.
