[RFC PATCH 1/1] pinctrl: imx: Reduce printk message level for empty nodes

[Alexander Stein <alexander.stein@xxxxxxxxxxxxxxx>]

iomuxc_snvs from imx6ull supports 2 boot mode and 10 tamper pins.
Probably most users won't use them, causing this error message during boot:
  no groups defined in /soc/bus@2200000/iomuxc-snvs@2290000
This is actually not an error in this case, so reduce the level
accordingly.

This issue was raised during release test: Why is there an error if
nothing is wrong?
Memory only devices are enabled by default, which I agree, but this
causes the mentioned error message unconditionally, unless some muxing is
configured. I would argue that even a warning is not correct either,
nothing is wrong here.
