The open-coded 64-bit division causes a link error on 32-bit

After all users of the 'dm' warnings got hidden in an #ifdef,
the compiler started warning about it being unused:

Selecting the chipidea driver from the old Kconfig symbol
can lead to a missing dependency:

Having both the driver and the unit test in the same module
leads to a link failure because of the extra init/exit functions:

I've come across this one again in linux-next today, and found that
I had an old patch for it already, that I had never submitted:

Not sure we care about the #ifdef here, given that arch/arm64 does not
allow building a kernel
