This driver actually does nothing but test pinctrl uclass, and
demonstrate how things work.

This commit adds dtsi file for Sandbox PMIC.
It fully describes the PMIC by:
- i2c emul node - with a default settings of 16 registers
- 2x buck regulator nodes
- 2x ldo regulator nodes
The default register settings are set with preprocessor macros:
- VAL2REG(min[uV/uA], step[uV/uA], val[uV/uA])
- VAL2OMREG(mode id)
Both defined in file:
- include/dt-bindings/pmic/sandbox_pmic.h
The Voltage ranges of each regulator can be found in:
- include/power/sandbox_pmic.h
The new file is included into:
- sandbox.dts
- test.dts

The file test.dts from driver model test directory,
was compiled by call dtc in script: test/dm/test-dm.sh.
This doesn't allow for including of dtsi files and using
of C preprocessor routines in this dts file.
Since the mentioned script builds U-Boot before tests,
then moving the test.dts file into sandbox dts directory
is reasonable.

The U-Boot device trees are slightly different in a few places. Adjust them
to remove most of the differences. Note that U-Boot does not support the
concept of interrupts as distinct from GPIOs, so this difference remains.
For sandbox, use the same keyboard file as for ARM boards and drop the
host emulation bus which seems redundant.

The 'lo' interface on Linux doesn't support thinks like ARP or
link-layer access like we use to talk to a normal network interface.
A higher-level network API must be used to access localhost.
As written, this interface is limited to not supporting ICMP since the
API doesn't allow the socket to be opened for all IP traffic and be able
to receive at the same time. UDP is far more useful to test with, so it
was selected over ICMP. Ping won't work, but things like TFTP should
work.

Implement a bridge between U-Boot's network stack and Linux's raw packet
API allowing the sandbox to send and receive packets using the host
machine's network interface.
This raw Ethernet API requires elevated privileges. You can either run
as root, or you can add the capability needed like so:
sudo /sbin/setcap "CAP_NET_RAW+ep" /path/to/u-boot
