dmaengine: dw_dmac: Add clk_{un}prepare() support
clk_{un}prepare is mandatory for platforms using common clock framework. Since this driver is used by SPEAr platform, which supports common clock framework, add clk_{un}prepare() support for it. Signed-off-by: Viresh Kumar <viresh.kumar@st.com> Signed-off-by: Vinod Koul <vinod.koul@linux.intel.com>
