Probably ARCH_MXC.

ARCH_MXC was originally the dependency for this driver, until it was changed
to a more specific one by
commit fcdba3c33a4d ("hwrng: imx-rngc - improve dependencies")

I don't think we'll see too many RNGB deployments in the future,
thus the list of SoCs shouldn't change that often.
