clk: qcom: camcc-x1e80100: Fix missing DT_IFACE enum in x1e80100 camcc

The desired DT pattern for clock indexing is the following:

clocks = <&gcc GCC_CAMERA_AHB_CLK>,
         <&bi_tcxo_div2>,
         <&bi_tcxo_ao_div2>,
         <&sleep_clk>;

In order to facilitate that indexing structure we need to have DT_IFACE
enum defined.
