Subject: [PATCH v3 11/11] ARM: davinci - common clock migration: clean up the old code
This patch clean up the obsoleted code after migrating to the
common clock framwork based code. Currently only dm644x is
supported as part of davinci_all_defconfig and other davinci
variants may not be buildable. But once all SoCs and machines
are migrated, some of these changes will be removed. However
this shows how the migration will happen.
