clk: qcom: Add support for divider flags and table

The clk-divider module in the clock framework provides support
for different kinds of dividers such as power-of-two and discrete
table based dividers. clk-regmap-divider module which adds regmap
support to the clk-divider doesn't handle the flags and table
parameters in the clk-divider that enables these divider types.
This change adds those two parameters to the clk-regmap-divider
struct and passes them to the clk-divider appropriately.
