This commit adds the asynchronous UART API testing support on the SAM
R21 Xplained Pro board.
The SERCOM3 module is used as the secondary loop-back UART, which is
required to run this test.
Note that no external UART loop-back connection is necessary to run
this test, because the SERCOM3 UART TX and RX pads are configured to be
internally connected; it is, however, still necessary to configure the
pinmux because the module pads are not connected until the pinmux is
configured.

In order to use its serial peripheral SERCOMs SAMD socs require their
pins to be configured with pinmux. Currently pins are muxed only for the
boards' default serial interfaces. The pinmux code is written to throw
a compiler error if a user tries to use any sercom in a way it wasn't
pre-defined to be used.
This commit changes compiler errors to warnings so that user can provide
custom pinmuxing code in their app.

When using internal IEEE 802.15.4 transceiver AT86RF233 at SPI speeds
above 6MHz was detected that frame buffer read returns corrupted data.
This set spi-max-frequency to 6MHz at atsamr21_xpro.dts to ensure best
relation of performance vs reliability.

Remove all "supported: -hwinfo" definitions from the boards
yaml files and documentation. hwinfo can generally be tested
on every board because it returns -ENOTSUP if not supported.

All board defconfig files currently set the architecture in addition to
the board and the SoC, by setting e.g. CONFIG_ARM=y. This spams up
defconfig files.
CONFIG_<arch> symbols currently being set in configuration files also
means that they are configurable (can be changed in menuconfig and in
configuration files), even though changing the architecture won't work,
since other things get set from -DBOARD=<board>. Many boards also allow
changing the architecture symbols independently from the SoC symbols,
which doesn't make sense.
Get rid of all assignments to CONFIG_<arch> symbols and clean up the
relationships between symbols and the configuration interface, like
this:
1. Remove the choice with the CONFIG_<arch> symbols in arch/Kconfig and
turn the CONFIG_<arch> symbols into invisible
(promptless/nonconfigurable) symbols instead.
Getting rid of the choice allows the symbols to be 'select'ed (choice
symbols don't support 'select').
2. Select the right CONFIG_<arch> symbol from the SOC_SERIES_* symbols.
This makes sense since you know the architecture if you know the SoC.
Put the select on the SOC_* symbol instead for boards that don't have
a SOC_SERIES_*.
3. Remove all assignments to CONFIG_<arch> symbols. The assignments
would generate errors now, since the symbols are promptless.
The change was done by grepping for assignments to CONFIG_<arch>
symbols, finding the SOC_SERIES_* (or SOC_*) symbol being set in the
same defconfig file, and putting a 'select' on it instead.
See
https://github.com/ulfalizer/zephyr/commits/hide-arch-syms-unsquashed
for a split-up version of this commit, which will make it easier to see
how stuff was done. This needs to go in as one commit though.
This change is safer than it might seem re. outstanding PRs, because any
assignment to CONFIG_<arch> symbols generates an error now, making
outdated stuff easy to catch.

Use this short header style in all Kconfig files:
# <description>
# <copyright>

...
Also change all <description>s from
# Kconfig[.extension] - Foo-related options
to just
# Foo-related options
It's clear enough that it's about Kconfig.
The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

This commit adds 'clock-frequency' property to the cpu nodes.
The clock frequency specified in the added property is used
during platform configuration. Examples:
- The SWO logger uses clock frequency to configure SWO output.
- Plenty of platforms need CPU clock specified for their HAL.
- Most of devices with USB needs information about CPU clock
in order to configure USB clock source.
