ARM: dts: samsung: exynos4210-i9100: Unconditionally enable LDO12

The kernel hangs for a good 12 seconds without any info being printed to dmesg, very early in the boot process, if this regulator is not enabled. Force-enable it to work around this issue, until we know more about the underlying problem.
