devfreq: Get rid of unused CONFIGs

Browse Source 
Remove the config variables as there is no Kconfig to define
these configs:
   CONFIG_DEVFREQ_GOV_WMARK_SIMPLE
   CONFIG_DEVFREQ_GOV_WMARK_ACTIVE

Remove the handling of non-module build as devfreq is always
build as module.

Remove the wmark-related devfreq governors as we plan to keep
them under drivers/gpu/drm/tegra. They are tightly bound with
the actmon and drm drivers.
