Rename adf_gen4_timer.c to adf_timer.c and adf_gen4_timer.h to adf_timer.h to make the files generation-agnostic. This includes renaming the start() and stop() timer APIs and macro definitions to be generic, allowing for reuse across different device generations. This does not introduce any functional changes.
