[PATCH] ARM: dts: imx6sl-evk: Keep VGEN1 regulator always enabled

On imx6sl-evk board the VGEN1 regulator powers up the NVCC_1.2V domain of the
imx6sl SoC, so we need to keep it always powered.

This problem has been observed by the fact that a GPIO connected to an LED could
not work when the PMIC driver was enabled.

Keeping VGEN1 regulator always enabled fixes the problem.
