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.
 - 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.

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 Wifi chip should be clocked by a 32kHz clock coming from i.MX7D
CLKO2 output pin, so describe the pinmux and clock hierarchy in the
device tree to allow the Wifi chip to be properly clocked.

Managed to successfully test Wifi with such change. Used the standard
nvram.txt file provided by TechNexion, which selects an external 32kHz
clock for the Wifi chip by default.

There's a bug in dtc in checking for duplicate node names when there's
another section (e.g. "/ { };"). In this case, skeleton.dtsi provides
another section. Upon removal of skeleton.dtsi, the dtb fails to build
due to a duplicate node 'fixedregulator@0'. As both nodes were pretty
much the same 3.3V fixed regulator, it hasn't really mattered. Fix this
by renaming the nodes to something unique. In the process, drop the
unit-address which shouldn't be present wtihout reg property.

The commit b1b8f45b3130 ("ARM: dts: bcm2837: Add missing GPIOs of Expander")
introduced a wifi power sequence. Unfortunately the polarity of the reset
GPIOs were wrong and broke the wifi support on Raspberry Pi 3 B and
later in 3 B+. This wasn't discovered before since the power sequence
takes only effect in case the relevant MMC driver is compiled as a module.
