kbuild: Allow to specify composite modules with modname-m
This allows to write drm-$(CONFIG_AGP) += drm_agpsupport.o without having to handle CONFIG_AGP=y vs. CONFIG_AGP=m. Only support this syntax for modules, since built-in code depending on something modular cannot work and init/Makefile actually relies on the current semantics. There are a few drivers which adapted to the current semantics out of necessity; these are fixed to also work when the respective subsystem is modular.
