Carlo Caione 6f9ca9c15a qemu_cortex_a53: Switch to GICv3
QEMU support for GICv3 is mature enough that we can switch to that by
default.

Ulf Magnusson c5839f834b kconfig: Remove assignments to CONFIG_<arch> syms and hide them
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outdated stuff easy to catch.
