gpio/samsung: correct pin configuration for S5PC100/S5PC110/EXYNOS4

Commit 1b39d5f introduced new common gpio driver for all Samsung GPIO
SoCs. The new driver use wrong configuration setup for all gpio pins on
S5PC100 and S5PV210 SoCs and external interrupt lines on Exynos4 SoCs.
This patch fixes this issue.
