ARM: SAMSUNG: Remove legacy clock code
Since S5PV210 now has a complete clock driver using Common Clock Framework, there is no reason to keep the old code. Remove it together with the whole legacy Samsung-specific clock framework which no longer has any users. Signed-off-by: Tomasz Figa <t.figa@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
