The LS1021A-TSN is a development board built by VVDN/Argonboards in
partnership with NXP.

It features the LS1021A SoC and the first-generation SJA1105T Ethernet
switch for prototyping implementations of a subset of IEEE 802.1 TSN
standards.

It has two regular Ethernet ports and four switched, TSN-capable ports.

It also features:
- One Arduino header
- One expansion header
- Two USB 3.0 ports
- One mini PCIe slot
- One SATA interface
- Accelerometer, gyroscope, temperature sensors

According to latest docs imx7d chips can go from 800 to 1200 mhz.
Maximum frequency is determined from two speed grading bits present in
OCOTP fuses at same location as other imx chips.

Also update to "typical" voltages from latest datasheet, 25mv higher
than current dts.

All imx7s parts are still fixed at 800mhz

The i2c2 bus has a external plug which enables the easy connection of external
"bricks" with sensors of various kinds, while i2c4 on the Extended/Full boards
has a pair of on board motion sensors, accelerometer and magnetometer on one chip
and gyroscope on another so it makes sense to enable these i2c buses for use.
Tested on UDOO Neo Full.

On i.MX7D SDB board, SW2 supplies a lot of peripheral devices,
its voltage should be fixed at 1.8V. The commit 43967d9b
("ARM: dts: imx7d-sdb: Assign corresponding power supply for LDOs")
assigns SW2 as the supplier of vdd1p0d, and when its comsumers
pcie-phy/mipi-phy try to set the vdd1p0d to 1.0V, regulator core
will also set SW2 to its best(min) voltage to 1.5V, and it will
lead to board reset.

This patch makes SW2's voltage fixed at 1.8V to avoid this issue.

While properties and child nodes with the same name are valid DT, the
practice is not encouraged. Furthermore, the collision is problematic for
YAML encoded DT. Let's just avoid the issue and rename the nodes.
