Previously the version string was special cased in the USB stack because the build system prevented the inclusion of ec_version.h in any file other than common/version.c. This lead to common/version.c being the only place that the USB version string could be computed and thus the special case of filling in the version string descriptor at run time. This made the USB stack more complex, and lead to the common/version.c file including usb.h, which is actually STM32 specific. Now, the portion of ec_version.h that is deterministic is only updated when something in the tree actually changes (by way of a conditional in the makefile), and ec_version.h no longer has to depend on all object files (other than the special version.o). This allows anyone to include ec_version.h as needed. In particular, each board that wants to define a USB version string can directly include ec_version.h and do so.
