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.

Since Mark is questioning this is a correct fix, I'm dropping it for
now.
