pinctrl: meson: fix unused variable warning

The kernel test robot reported a warning as below:
>> drivers/pinctrl/meson/pinctrl-meson-s4.c:178:27: warning: unused variable 'tdm_sclk1_c_pins' [-Wunused-const-variable]
   static const unsigned int tdm_sclk1_c_pins[]            = { GPIOC_3 };

Fix it by adding missing description about this pins
