Is there a reason not to keep "default ARCH_BERLIN"?

Hi,
After this patch, the reset driver will be built as module in most cases
so I removed default ARCH_BERLIN
Thanks

I see, how about "default m if ARCH_BERLIN" then?
I'd just like to avoid anybody getting surprised by a suddenly
deactivated reset controller driver.

Good idea. I think "default m" is enough, because we have a "depends on
ARCH_BERLIN || COMPILE_TEST" above
Will send out v2 soon

"default m" would also enable the module for COMPILE_TEST by default,
which may not be what most compile testers need.
