gpio/samsung: Fix incorrect gpio pull up/down callback for EXYNOS4
Some of the gpio chips of exynos4 are assigned a default gpio config without the exynos4 specific pull up/down callbacks which resulted in incorrect setting of pull up/down configuration. Fix this by adding two new exynos4 specific entries in the array of default configs with set_pull and get_pull callbacks set to exynos4 specific callbacks The new default gpio configs can then be used for exynos4 gpio chips.
