drivers: clk: st: Add CLK_GET_RATE_NOCACHE flag to clocks
Add the CLK_GET_RATE_NOCACHE flag to all the clocks with recalc ops, so that they reflect Hw rate after CPS wake-up when a clk_get_rate() is called Signed-off-by: Pankaj Dev <pankaj.dev@st.com> Signed-off-by: Gabriel Fernandez <gabriel.fernandez@linaro.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
