This patch converts the TPC70 to use driver model and device tree
description in both SPL and u-boot proper.
Notable changes (DM/DTS conversion):
- PINCTRL{_IMX6}
- DM_I2C
- enable 'regulator' and 'pmic' commands
- DM_MMC and BLK (USDHC)
- DM_ETH
- DM WDT (including SYSRESET)

The TPC70 can boot from SD card (debug/development) and eMMC (production).
The board_boot_order() function provides a run time check for the device
from which one wants to boot (it is selected by GPIO pins setup).
Moreover, a fallback to SD card is provided if the detection is not
possible or working properly.

This header file is now only used by files that access internal
environment features. Drop it from various places where it is not needed.

This setup is a bit special as Linux kernel (4.19) is not supporting
in-kernel NFS rootfs mount and Distributed Switch Architecture (DSA)
operation.
For that reason it was necessary to provide a bootarg to allow userspace
enable it afterwards if needed.

As EHCI on i.MX5 has been converted to driver model, the board specific
code, necessary for VBUS USB power supply setup is not needed anymore.

The serverip part is provided from DHCP server with
'option root-path "192.168.3.1:/srv/tftp/rootfs";' parameter in dhcpd.conf

The quotes around ${bootargs} were missing as we elaborate those variables
twice - once when we "setenv" the command and secondly when we "run" it.
Without quotes we have just empty string in the second call.
Moreover there is an issue with line breaks - as the original commands
got truncated.

The 'dhcp' command is more versatile as it allows working with the DHCP
server to obtain serverip, ipaddress and other network parameters.
The configuration necessary to obtain the serverip (dhcpd.conf):
option option-150 code 150 = ip-address;
and in the subnet definition:
option option-150 192.168.X.Y;

The 'rootpath' can be provided by DHCP server. Removing this line prevents
from overwriting it.
To do that on the DHCP server side (isc-dhcp-server) modify dhcpd.conf
and add 'option root-path "192.168.X.Y:/srv/tftp/rootfs";'

This patch prevents from the situation where we may end up with garbage
displayed on the LCD panel.
Such situation occurs when one performs "reboot -f" in Linux and then
stop in U-boot (or observe the garbage on the screen during boot up).
To prevent from such situation - the PWM pin is configured as GPIO and set
to LOW.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

By using this file one can avoid cluttering <board>.h file with u-boot
HUSH commands necessary for booting target device.
With such approach the commands are stored only in one place and can be
reused if needed.
