sgtl5000 codec needs MCLK clock to be provided so that it can
successfully read/write via I2C, so we should better let the
codec control the pinctrl for such pin.

Thanks to Stefan Agner who provided the fix on Toradex's tree:

imx7s-warpd has WDOG1_B pin connected to the PMIC.

Pass the 'fsl,ext-reset-output' property so that the watchdog
can trigger a system POR reset via the PMIC.

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.
