The mxs pinctrl driver cannot handle when functions are not grouped by
name (which IMO is a bug). This happens for example if a
imx28-somemachine.dts provides a function that has the same name as a
function defined in imx28.dtsi.
The proper way to fix that would be to check for duplicates in the loops
(which increases parsing time) or parse the groups first and sort the
resulting array.

Add pinmux support for GPIO for Vybrid (vf610) IOMUX controller.
This is needed since direction configuration is not part of the
GPIO module in Vybrid.

The pinctrl driver initialized the register offsets for the pins
with 0. On Vybrid an offset of 0 is a valid offset for the pinctrl
mux register. So far, this was solved using the ZERO_OFFSET_VALID
flag which allowed offsets of 0. However, this does not allow to
verify whether a pins struct imx_pmx_func was initialized or not.
Use signed offset values for register offsets and initialize those
with -1 in order to detect uninitialized offset values reliable.

This moves all the Freescale-related drivers (i.MX and MXS) to
its own subdirectory to clear the view.
