This patch enable convert DM MMC for imx7d-pico board and variant.
Before the DM conversion only usdhc3 was enabled and therefore it appeared
as MMC 0 to u-boot. After enabling MMC DM though usdhc3 defaults to MMC 2,
which left unattended would drive changes to existing pico-pi bootscripts and
environment variables that rely on mmc 0.
Setup the alias of mmc0 and usdhc3 so that existing pico-imx7d boot code will
work unmodified.
When converting to DM_MMC it is necessary that SPL initializes eMMC
by itself, so move the original eMMC initialization from U-Boot
proper to SPL.

Since commit 9e3c0174da ("pico-imx7d: Add LCD support") we started to
notice some hangs in U-Boot.
There is not an issue on such commit per se, but due to the LCD support
the current drawn is increased and this may cause issues when powering
pico-imx7d-pi from USB.
Some computers may be a bit strict with USB current draw and will
shut down their ports if the draw is too high.
The solution for that is to use an externally powered USB hub between the
board and the host computer.
Add such recommendation to the README file.

After the DM_MMC conversion the following eMMC boot error is observed:
U-Boot SPL 2019.04-rc4 (Mar 20 2019 - 18:53:28 +0000)
Trying to boot from MMC1
MMC Device 0 not found
spl: could not find mmc device 0. error: -19
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###
This happens because the SPL code does not initialize the SDHC pins
and clock.
Fix it by moving the original eMMC initialization from U-Boot proper
to SPL.

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.

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.
