clk: qcom: remove unused data from gcc-ipq5424.c

The newly added driver causes a warnings when enabling -Wunused-const-variables:

drivers/clk/qcom/gcc-ipq5424.c:1064:30: error: 'ftbl_gcc_q6_axi_clk_src' defined but not used [-Werror=unused-const-variable=]
 1064 | static const struct freq_tbl ftbl_gcc_q6_axi_clk_src[] = {
      |                              ^~~~~~~~~~~~~~~~~~~~~~~
drivers/clk/qcom/gcc-ipq5424.c:957:30: error: 'ftbl_gcc_qpic_clk_src' defined but not used [-Werror=unused-const-variable=]
  957 | static const struct freq_tbl ftbl_gcc_qpic_clk_src[] = {
      |                              ^~~~~~~~~~~~~~~~~~~~~
drivers/clk/qcom/gcc-ipq5424.c:497:30: error: 'ftbl_gcc_qupv3_2x_core_clk_src' defined but not used [-Werror=unused-const-variable=]
  497 | static const struct freq_tbl ftbl_gcc_qupv3_2x_core_clk_src[] = {
      |                              ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

In order to hopefully enable this warning by default in the future,
remove the data for now. If it gets used in the future, it can
trivially get added back.
