UHS-I support is available on Ventana boards with micro-SD sockets depending
on the board revision. To support this pinctl states for 100Mhz and 200MHz
must be added as well as pinmux of the VSELECT signal. In order to support
UHS-I the I/O rail of the 4-bit data bus must be switchable between 1.8V
and 3.3V.
By adding the no-1-8-v property, which disables UHS-I support, we allow the
bootloader to be in charge of selecting which boards have this capability
by removing that property if the board model/revision implement the support.
Additionally we will remove NANDF_CS1 here from the nand pinmux group as the
second chip-select is not used on any ventana boards and this is the pad
that is used for SD3_VELECT.

Follow the conventions for pinctrl:
- grouping pinctrl in logical alphabatized groups
- remove any pinctrl not being used by a driver or needed by user
- move iomuxc to bottom of file for readability

The general device-tree rule is to not include nodes that do not have a driver
or bindings in a dts/dtsi. Remove the place-holder nodes from the Gateworks
Ventana boards until a time that a driver with proper bindings exists.

The Gateworks Ventana product family consists of several baseboard designs
based on the Freescale i.MX6 family of processors. Each baseboard has a
different set of possible features.
