gpio: tangier: calculate number of ctx using temporary variable
Utilize a temporary variable to calculate number of ctx from ngpio inside ->probe() implementation. While at it, include math.h for using DIV_ROUND_UP(). Signed-off-by: Raag Jadav <raag.jadav@intel.com> Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>
