You should (try to) justify default m, otherwise just
don't have a default for it.
I have chosen default m since many other Dell platform drivers are being
default m. Since this driver is not essential for normal operation,
i will drop default m then.
Actually Dell drivers directory are a bit unique in this regard. There is a special
top level boolean. I would suggest to keep it as is.

Take a look at:
menuconfig X86_PLATFORM_DRIVERS_DELL

Ok.
