pinctrl: qcom: spmi-gpio: Mark expected switch fall-through 

When fall-through warnings was enabled by default the following warnings
was starting to show up:

../drivers/pinctrl/qcom/pinctrl-spmi-gpio.c: In function ‘pmic_gpio_populate’:
../drivers/pinctrl/qcom/pinctrl-spmi-gpio.c:815:20: warning: this statement may fall
 through [-Wimplicit-fallthrough=]
   pad->have_buffer = true;
   ~~~~~~~~~~~~~~~~~^~~~~~
../drivers/pinctrl/qcom/pinctrl-spmi-gpio.c:816:2: note: here
  case PMIC_GPIO_SUBTYPE_GPIOC_4CH:
  ^~~~
../drivers/pinctrl/qcom/pinctrl-spmi-gpio.c:820:20: warning: this statement may fall
 through [-Wimplicit-fallthrough=]
   pad->have_buffer = true;
   ~~~~~~~~~~~~~~~~~^~~~~~
../drivers/pinctrl/qcom/pinctrl-spmi-gpio.c:821:2: note: here
  case PMIC_GPIO_SUBTYPE_GPIOC_8CH:
  ^~~~

Rework so that the compiler doesn't warn about fall-through.
