pinctrl: intel: Fix kernel doc format, i.e. add return sections
Kernel doc validator is not happy: pinctrl-intel.c:865: warning: No description found for return value of 'intel_gpio_to_pin' pinctrl-intel.c:904: warning: No description found for return value of 'intel_pin_to_gpio' 2 warnings Add return sections to the kernel documentation of the above mentioned functions.
