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.
