To establish a connection between GPIO controllers and pin multiplexor
controller add gpio-ranges properties to all GPIO controllers found
on iMX50, iMX6Q/D, iMX6DL/S, iMX6SL, iMX6SX, iMX6UL and iMX7D/S
SoCs. The change was done after human parsing of output from
% gawk -n '{ sub(/.*__/, ""); if ($1 ~ "^GPIO") print $1, $2/4}' imxXX-pinfunc.h | sort -n

Only i.MX 7Dual SoC supports CPU frequencies of up to 1GHz. The i.MX
7Solo can run with up to 800MHz and does so without making use of DVFS
usually. While the device tree clearly specified a too fast operating
point for i.MX 7Solo, the kernel did not used it in practise so far
because the CPUfreq driver does not get loaded on i.MX 7Solo devices
(since the fsl,imx7s compatible string is not in the list of devices
making use of the cpufreq-dt driver...).

The i.MX 7 as a GICv2, hence its CPU interface register map (the
second register region) is 8kB long. Add the VGIC maintenance
interrupt which allows to use the new VGIC driver.

Since we have a SoC level node we should make use of it and have
all nodes which are within the SoC, inside that node. This also
saves an extra interrupt-parent properties. While at it, also
order the Coresight nodes according to register addresses.

The base device tree uses KEY_POWER in the snvs-powerkey node,
hence include the input.h header file in the base device tree.

The i.MX 7Solo implements a subset of features available on
i.MX 7Dual. Recreate imx7s.dtsi as the base device tree for
i.MX 7Dual boards. The i.MX 7Dual's additional features over
i.MX 7Solo are:
- Second Cortex-A7 core
- Second Gigabit Ethernet controller
- EPD (Electronc Paper Display, not yet part of the device tree)
- PCIe (not yet part of the device tree)
- Additional USB2.0 OTG controller

The i.MX 7 series currently consists of two SoCs: i.MX 7Solo and
7Dual. The former has a subset of features of the latter, hence
use imx7s.dtsi as the new base device tree. To keep diffstat nice,
just move imx7d.dtsi to imx7s.dtsi temporarily and recreate
imx7d.dtsi in a second commit.
