pinctrl: samsung: Fix pinctrl bank pin count

Commit 1abd18d1a51a ("pinctrl: samsung: Register pinctrl before GPIO")
changes the order of GPIO and pinctrl registration: now pinctrl is
registered before GPIO. That means gpio_chip->ngpio is not set when
samsung_pinctrl_register() called, and one cannot rely on that value
anymore. Use `pin_bank->nr_pins' instead of `pin_bank->gpio_chip.ngpio'
to fix mentioned inconsistency.
