- A couple of fixes on imx7d-pico and imx7d-nitrogen7 boards to correct
the description of the Wifi clock.
- Change SW2ISO count to get a safer ARM LDO ramp-up time, so that
different boards can be covered. This fixes the ARM LDO failure seen
on some customer boards.

i.MX fixes for 4.20, round 3:
- A couple of fixes on imx7d-pico and imx7d-nitrogen7 boards to correct
the description of the Wifi clock.

Boards based on imx7 have duplicate memory nodes:
- One coming from the board dts file: memory@
- One coming from the imx7s.dtsi file.
Fix the duplication by removing the memory node from the dtsi file
and by adding 'device_type = "memory";' in the board dts.

According to bindings/regulator/fixed-regulator.txt the 'clocks' and
'clock-names' properties are not valid ones.
In order to turn on the Wifi clock the correct location for describing
the CLKO2 clock is via a mmc-pwrseq handle, so do it accordingly.

The i.MX7 has two iomux controllers. the iomuxc and the iomuxc_lpsr.
In a board dts we have to make sure that both controllers are supplied
with the correct pins. It's way too easy to do this wrong since only
a look into the reference manual can reveal which pins belong to which
controller. To make this clearer add "LPSR" to the pin names which
belong to the LPSR controller.

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.

As of commit 1006ed7e1b ("serial: imx: Use generic uart-has-rtscts
DT property"), the Freescale IMX UART driver recognizes the generic
"uart-has-rtscts" DT property, deprecating the vendor-specific
"fsl,uart-has-rtscts" DT property. Hence replace the latter by the
former in all DTS files.
