With the recent cleanup in Exynos platform code notably commits
17859bec ("ARM: EXYNOS: Do not select legacy Kconfig symbols any
more") and b9222210 ("ARM: EXYNOS: Remove mach/gpio.h"), the definition
of ARCH_NR_GPIOS got removed. This started causing problems on SoCs like
Exynos4412 which have more than the default number of GPIOs. Thus define
this number in KConfig file. Without this patch we get the following errors
during boot:

gpiochip_add: gpios 251..258 (gpv0) failed to register
samsung-pinctrl 106e0000.pinctrl: failed to register gpio_chip gpv0,
error code: -22
samsung-pinctrl: probe of 106e0000.pinctrl failed with error -22

Changes since v1:
* Changed default number to 285 (as required by 4412).
