The SAM4L have a unique I2C driver. It shares simultaneously pins for
both master and slave controllers. Each controller have their own
instance. This introduces the TWIM controller that handles only the
master part.
The TWIM controller uses no copy and the driver was prepared to work
with both 7 and 10 bits address. The controller can handler up to 256
bytes for a single transfer allowing long data communication with
almost no CPU intervention.
The driver was wrote specifically to Zephyr. It receives a transfer
list of from upper layers to a specific device on the bus. It programs
the first and second transfer, if it exists, before start. At end of
full read/write interrupt, will program the next data block. This
process repeats until all transfers be executed. The driver uses
interrupt from TWIM to check for erros or program next tranfer.
Future work can enable low power mode on the driver allowing long
transfers with low power consumption.

The SAM V71 SoC configuration currently selects the `ARM_MPU` symbol
and this effectively forces MPU usage on the SoC.
This commit removes `ARM_MPU` selection from the SoC Kconfig since it
is intended to be selected by a board, and the `CPU_HAS_ARM_MPU` symbol
already indicates that the SoC supports ARM MPU.

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.
