I see that now.  Quite bizarre how the NS2 pinctl driver (used on a 
arm64 SoC) gets built right now....

Yes, adding the select with hidden option seems like what needs to be 
done.  The ARM Maintainers did not like multi-level ARCH_BCM being added 
in the arm64 Kconfig previously so we dropped it.
