From: Laurentiu Tudor <laurentiu.tudor@nxp.com>

The driver makes use of GENERIC_MSI_IRQ_DOMAIN which requires arch
support so, on architectures that don't have it, the kernel will fail
to build. Add explicit dependency on architectures that were
compile-tested, thus fixing compilation for the ones that don't
implement GENERIC_MSI_IRQ_DOMAIN.

Fixes: 03274850279c ("staging: fsl-mc: allow the driver compile multi-arch")

 - This should take care of the compilation issue that Stephen Rothwell
   reported here: https://lkml.org/lkml/2017/7/31/200
 - Note that ppc will compile after merge with the powerpc tree because
   this patch is required: https://patchwork.ozlabs.org/patch/789474/
