Subject: [PATCH -next] clk: qcom: fix build error initializer element is not constant

CONFIG_CC_VERSION_TEXT="x86_64-linux-gnu-gcc (Ubuntu 7.4.0-1ubuntu1~18.04.1) 7.4.0"
make ARCH=x86_64 CROSS_COMPILE=x86_64-linux-gnu-, will be failed, like this:

drivers/clk/qcom/gpucc-sm8350.c:111:2: error: initializer element is not constant
  gpu_cc_parent,
  ^~~~~~~~~~~~~
drivers/clk/qcom/gpucc-sm8350.c:111:2: note: (near initialization for ‘gpu_cc_parent_data_0[0]’)
drivers/clk/qcom/gpucc-sm8350.c:126:2: error: initializer element is not constant
  gpu_cc_parent,
  ^~~~~~~~~~~~~
drivers/clk/qcom/gpucc-sm8350.c:126:2: note: (near initialization for ‘gpu_cc_parent_data_1[0]’)
make[3]: *** [drivers/clk/qcom/gpucc-sm8350.o] Error 1

It seems that nested constant initializer is not supported in GCC 7.4.0. For portability resons, we should fix it.
