arm64: dts: imx8x-colibri: mark usdhc2 with no-1-8-v
The original Colibri family module standard never supported switching
the SD card interface to 1.8 volt signalling. And as all former carrier
boards do have 3.3 volt pull-up resistors on the command- and data-lines
of SD-signals this is also not compatible with all UHS modes. Mark this
module as not compatible with 1.8 volt signalling with the no-1-8-v tag.
Should you be lucky and have a custom carrier board or Iris v2 which
does not have such 3.3 volt pull-ups (or you removed yours) one may
explicitly delete this property again.
While at it also alphabetically re-order them usdhc2 properties.
