clk: qcom: Consolidate common probe code
Most of the probe code is the same between all the different clock controllers. Consolidate the code into a common.c file. This makes changes to the common probe parts easier and reduces chances for bugs. Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Mike Turquette <mturquette@linaro.org>
