On many B&R boards we have a reset-controller, responsible for very
early board-bringup (voltages, clocks, ...) and bootmode selection.
To be ready for adding more B&R boards to source tree while avoiding
duplicate code, we add the resetcontroller implementation to the common
part of B&R boards.

Many B&R boards are equipped with an I2C-EEPROM where various
information can be stored.
Today there is only a single byte for 'board_id' used.
We write this 'board_id' into environment for later use during boot.
If the value != 0xFF, meaning the byte is programmed, we modify the
"brdefaultip" environment variable for setting an IP-Address based on
board_id.

This commit converts the brxre1 board to DM,
for this we have todo following things:
- add a devicetree-file for this board
- drop all obsolete settings from board header-file
- use dm_i2c_xxx calls for read/write to the resetcontroller
- request gpios before operate them

On other OS, not one provided by B&R, it is not guaranteed that there
are factory-settings within a devicetree. So we must not treat the
absence of them as error.
Further we've the fact that on different version of the device-tree
files there are different namings of the factory-settings, we consider
this with searching for an alternative name.
changing things as following:
- don't treat as error if the bootloader version cannot written into
devicetree.
- since the naming of the factory-settings are different in different
versions of the provided device-tree we search for the alternate name

If a board-code calls the pmicsetup(u32 mpupll) with a mpupll value
!= 0 it wants to force some frequency with the value provided by mpupll.

- drop the common dtb loading mechanism
- drop the now obsolete CONFIG_USE_FDT from board header and whitelist.

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.

This fixes failures such as:

board/ti/am335x/board.c:752: undefined reference to `eth_env_set_enetaddr'

To keep a consistent MMC device mapping in SPL and in u-boot, let's
register the MMC controllers the same way in u-boot and in the SPL.
In terms of boot time, it doesn't hurt to register more controllers than
needed because the MMC device is initialized only prior being accessed for
the first time.
Having the same device mapping in SPL and u-boot allows us to use the
environment in SPL whatever the MMC boot device.

Since the used AM3352 SoC doesn't have GPU it isn't allways necessary to build
in complete drm-stuff into linux kernel. In very small applications only we use
the simple-framebuffer.
So we have 2 use-cases:
- device operating on drm-driver (let simplefb node disabled)
- device operating on simplefb-driver (activate simplefb node and reserve mem)
The decision is made by means of "simplefb" environment variable.
simplefb = 0
we don't enable the (maybe) existing simplefb node and all the rest around
display is up to the linux-kernel. We just disable the backlight, beceause we
do not want see the flicker during take over of drm-driver.
simplefb = 1
we enable the (maybe) existing simplefb node and reserve framebuffers size
in memory.
