Avoid UART input from floating RX pins on UARTB and UARTC (Colibri T30)
and UARTB, UARTC and UARTD (Apalis T30).
Note: Floating pins may cause spurious break conditions potentially
interrupting U-Boot's autoboot.

Fix SPI1 and UART2/3 resp. UARTB/C pinmuxing.
Note: The former was illegally muxing multiple SoC balls onto the same
internal SoC signal which caused rather strange behaviour regarding
the RS232 serial transceiver ForceOFF# pins as available on Iris.

Add pinmuxing comment stating that TRISTATE means the output driver is
tri-stated and INPUT means the input driver is enabled vs. OUTPUT where
it is disabled.

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.

In a number of places we had wordings of the GPL (or LGPL in a few
cases) license text that were split in such a way that it wasn't caught
previously. Convert all of these to the correct SPDX-License-Identifier
tag.
