The SAM0 series has up to 6 SPI ports. Add Kconfig options to match.
Similar to the 9033fb2f01, this patch
only defines the fields that are currently used and skips ones like
GPIO and IRQ priority that aren't.

1. Read notification attributes set by server to setup the
minimum/maximum notification period of a observation request.
2. Reordering to check observe_node duplication first
(bailout earlier)
3. Simplify remove observe_node condition checking

from server side (implement lwm2m_write_attr_handler accordingly)

We don't need to store the full k_mem_block, rather just the
k_mem_block_id. In effect, this saves 4 bytes of memory per allocated
memory chunk. Also take advantage of the newly introduced
k_mem_pool_free_id API here.
Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
The k_mem_pool_free API has no use for the full k_mem_block struct. In
particular, it only needs the k_mem_block_id. Introduce a new API
which takes only this essential struct. This paves the way to
simplify & improve the k_malloc/k_free implementation a bit.

When Kconfiglib was introduced it caused a significant performance
issue. This patch uses pruning to mitigate the performance issue.
The pruning exploits the fact that before the Kconfig database is
parsed we already know what ARCH and BOARD has been selected. So in
theory we could prune away all Kconfig sources that are not related to
the current ARCH or BOARD. In practice, it is only the Kconfig sources
in zephyr/arch/$ARCH and zephyr/board/$ARCH/ that are easy to prune.
Still, that is quite a few Kconfig sources. For qemu_x86 this patch
reduced the number of parsed Kconfig source files from 632 to
272. This pruning resulted in a incremental reconfiguration (time
cmake ..) speedup of 21% (0.56s to 0.46) and a clean build speedup of
4% (Using board qemu_x86 and sample hello_world).
Furthermore, it should be easier to maintain ARCH's and BOARD's
out-of-tree since the user now has a mechanism to redirect where
Kconfig sources are found. But this has not been explored.

Kconfiglib does not support merging fragments without parsing the
entire Kconfig "database". For Zephyr this means we no longer get a
performance gain from splitting up the fragment-merging and the
.config generation.
This patch removes the seperated merge step and it's associated
caching mechanism. Now we do a full Kconfig execution on every
reconfiguration.

We have been using a fork of the Linux kernel's Kconfig system to
configure the Zephyr tree. The issue is that this is a native tool

uses Kconfiglib to generate the .config and autoconf.h files required to
compile Zephyr.

SPI_MODE_GET() returns a bitfield. It is thus wrong to test if a bit is
set using the equality operator. The bit-wise AND operator must be used
instead.
This can be tested by setting the SPI in mode 3 (CPOL + CPHA). Currently
both tests will fail and the result is a SPI configured in mode 0. This
was confirmed using an oscilloscope. Applying the patch fixes the
polarity.
