[PATCH/RFC] rapidio: temporarily exclude FSL_RIO from 64 bit builds

[Paul Gortmaker <paul.gortmaker@windriver.com>]

The following are seen while using the corenet64_smp_defconfig:

arch/powerpc/sysdev/fsl_rmu.c:315: error: cast from pointer to integer of different size
arch/powerpc/sysdev/fsl_rmu.c:320: error: cast to pointer from integer of different size

arch/powerpc/sysdev/fsl_rmu.c:659: error: format '%8.8x' expects type 'unsigned int', but argument 5 has type 'size_t'
arch/powerpc/sysdev/fsl_rmu.c:985: error: cast from pointer to integer of different size
arch/powerpc/sysdev/fsl_rmu.c:997: error: cast to pointer from integer of different size

A quick inspection of the code leaves one with the impression
that it was not explicitly written with 64 bit support in mind,
so just block that as a possible config selection for now.

[This is seen in linux-next -- not sure if this is the right way to go
 but at least it will give the issue some visibility to the right ppl.]
