[PATCH 2/2] drivers/clk/clk_zynqmp.c: get rid of compiler warning for !CONFIG_CMD_CLK builds

[Peter Korsgaard]

When built without CONFIG_CMD_CLK, we get a warning about the unused
clk_names variable:

../drivers/clk/clk_zynqmp.c:153:27: warning: ‘clk_names’ defined but not used [-Wunused-const-variable=]
  153 | static const char * const clk_names[clk_max] = {

So also guard it with CONFIG_CMD_CLK to get rid of that.
