ARM: dts: exynos: Fix mismatched value for SD4 pull up/down configuration on exynos4210
The pinctrl pull up/down register on exynos4210 is 2-bit wide for each pin and it accepts only values of 0, 1 and 3. The pins sd4-bus-width8 were configured with value of 4. The driver does not validate the value so this overflow effectively set a bit 1 in adjacent pins thus configuring them to pull down. The author's intention was probably to set drive strength of 4x. All other bus-widths pins are configured with pull up and drive strength of 4x. Fix this one with same pattern.
