The SoC node has compatibles for the specific SoC in place, having the
same compatible at the top level is technically a conflict and the
top-level one should really just be about the board. Remove the SoC
related compatibles at the top-level.

Kconfig options that enable I2C and SPI instances are no longer used
in nRF drivers. Remove all assignments done to these options in related
board definitions, samples, and tests.
For nrf52_pca20020, also no longer needed setting of default values
for GPIO_SX1509B* options is removed (now the gpio_sx1509b driver is
enabled by default when a corresponding devicetree node is enabled).

Remove prompts from Kconfig options `UART_x_NRF_UART*` that select
the type of nrfx driver (for UART or UARTE peripheral) to be used
for a given instance. This prevents the options from being modified
from configuration files.
Instead, make one of these options selected by default according to the
"compatible" property set for the corresponding UART node in devicetree.
This eliminates the need of changing both the "compatible" property in
devicetree and the Kconfig option selecting the driver type when a user
wants to switch between UART and UARTE for a given instance.
Since all `UART_x_NRF_UART*` options are made "hidden" by this commit,
all their occurrences in configuration files are removed.

Same deal as in commit eddd98f ("kconfig: Replace some single-symbol
'if's with 'depends on'"), for all symbols defined within defconfig
files. See that commit for an explanation.
Maybe 'if's were used originally to mirror the 'if's in the main Kconfig
files, and then it got copied around by people assuming 'if' must work
differently from 'depends on'. It doesn't match in every spot at least.
Better to keep it simple and just consistently use 'depends on' when
it's a single symbol/choice I think. Helps reinforce that 'if' isn't
magic too.
Verified by printing all Kconfig menu nodes (symbols, choices, menus,
etc.) before and after the change and diffing (should show no
difference).

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.

This commit introduces separate "compatible" strings for DTS nodes
representing different types of Nordic SPI peripherals. Previously
"nordic,nrf-spi" was used for both SPI and SPIM. SPIS was already
handled separately.
Quite a few files need to be touched by this commit but the changes can
be divided into groups of related or very similar ones, distinguishable
by the initial part of the path to the modified file:
* dts/bindings/spi/
new binding for "nordic,nrf-spim" is added and common fields for all
3 types of Nordic SPI peripherals are extracted to a shared file
* dts/arm/nordic/
"compatible" properties in spiX nodes are updated (when there is no
choice as only one type of SPI peripheral is available) or replaced
with a comment pointing out that the proper type of peripheral needs
to be picked at some upper layer
* drivers/spi/
spi_nrfx_spim driver is updated with the new form of macros generated
from dts
* boards/
all spiX nodes in dts files for boards equipped with an nRF chip are
updated with the proper "compatible" property, according to the type
of SPI peripheral that is currently selected for the board by the
corresponding Kconfig choice option (SPI_x_NRF_SPI*)

The DT spec. only has "okay" and not "ok". The Linux kernel has around

Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier. Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.

This patch enables the GPIO driver by default on all boards equipped
with an nRF SoC (all boards having `CONFIG_SOC_FAMILY_NRF=y` in their
`_defconfig` file).
In vast majority of cases the driver is needed, so it is more
convenient to enable it at board level than in particular
applications.
And if the driver is undesired for some reason, it can be still
disabled in the application config.
