gpio: samsung: adapt to changes in gpio specifier translator function declaration 

Commit 15c9a0acc3 (of: create of_phandle_args to simplify return of phandle
parsing data) modifies the parameter list of of_xlate function pointer declaration
in gpio_chip. Adapt the gpio specifier translate function for this change.
