regulator-(min|max)-microvolt refer to the supported voltages according
to board design, not the possible range of the regulators themselves.
Update the configuration for the TQMa7x's PMIC and also add a comment
regarding the PMIC's VCC_SD switching feature.
Fixes: a80a1af6ec8a ("ARM: dts: tq imx7 common board support")

I think make sense, but any document or mail list can be refer to?

Hi Frank,
I've occasionally seen this being mentioned in reviews like [1] when the
regulator-min/max was used incorrectly. The binding docs [2] say:
regulator-min-microvolt:
description: smallest voltage consumers may set
regulator-max-microvolt:
description: largest voltage consumers may set
which is not as clear as I would like... Right now I don't have a source that
feels definitive enough to include it in the commit description.
Best,
Nora

I suggest create patch to make it clearer, and check what said by dt team
and Mark. If they agree your change, we can refer it in future.
