This is not the general pattern for on-CPU devices on the embedded SoCs,
for those we normally only offer the config option when building for a
system which could physically have the device.  Looking at the existing
MMC host drivers you'll see this pattern is already heavily used there -
all the existing embedded controllers have similar dependencies.

No, I didn't even try to build it - I saw that I was being offered a
device for a Marvell CPU when building for a non-Marvell CPU.
