    dell-laptop: Use dell-rbtn instead i8042 filter when possible

causes build errors:

  LD      init/built-in.o       
drivers/built-in.o: In function `dell_init':
/usr/src/linux-next/drivers/platform/x86/dell-laptop.c:762: undefined reference to `dell_rbtn_notifier_register'
/usr/src/linux-next/drivers/platform/x86/dell-laptop.c:2016: undefined reference to `dell_rbtn_notifier_unregister'
drivers/built-in.o: In function `dell_exit':
/usr/src/linux-next/drivers/platform/x86/dell-laptop.c:2041: undefined reference to `dell_rbtn_notifier_unregister'

when built with:

CONFIG_DELL_LAPTOP=y
CONFIG_DELL_RBTN=m

because the builtin then references a symbol that's in a module.

Probably needs some Kconfig magic to ensure this case doesn't happen.
