`cpu/stm32_common/Makefile.dep` was never included by the global `Makefile.dep`, so declaring this `USEMODULE +=` here was never shown to the build system and never exported as `MODULE_PERIPH_I2C_X` variables. In fact, `USEMODULE` was only used to trigger the `periph.mk`/`SUBMODULES` mechanism to add matching source files names to `SRC` and so select the implementation for each CPU type. It is replaced by just explicitly selecting the right source file.
