Add API for recovering an I2C bus. This API can be used to recover
from situations where the I2C master and one or more I2C slaves are
out of synchronization (e.g. if the I2C master was reset in the middle
of an I2C transaction or if a noise pulse was induced on the SCL
line).
Fixes#23441.

init_fn is not anymore part of struct device, so let's test instead the

When the device driver model got introduced, there were no concept of
SYS_INIT() which can be seen as software service. These were introduced
afterwards and reusing the device infrastructure for simplicity.
However, it meant to allocate a bit too much for something that only
required an initialization function to be called at right time.
Thus refactoring the devices structures relevantly:
- introducing struct init_entry which is a generic init end-point
- struct deviceconfig is removed and struct device owns everything now.
- SYS_INIT() generates only a struct init_entry via calling
INIT_ENTRY_DEFINE()
- DEVICE_AND_API_INIT() generates a struct device and calls
INIT_ENTRY_DEFINE()
- init objects sections are in ROM
- device objects sections are in RAM (but will end up in ROM once they
will be 'constified')
It also generate a tiny memory gain on both ROM and RAM, which is nice.
Perhaps kernel/device.c could be renamed to something more relevant.

With the new RI-2018.0 XCC, xt-gdb complains about not being able

issued. So swap these two commands in the load_elf.txt file.

This commit introduces backward compatibility with Zephyr SDK 0.11.1
and 0.11.2 so that users having one of those versions installed can
continue to use that version.
This remove the need to force users to update their SDK.
This is kept in independent commit to ensure it can easily be reverted
when minimum required Zephyr SDK is bumped to version 0.12.

This commit introduces Zephyr SDK CMake config package.
This removes the need for setting ZEPHYR_SDK_INSTALL_DIR and
ZEPHYR_TOOLCHAIN_VARIANT when using Zephyr SDK in Linux.
It also allows to introduces never SDKs without breaking Zephyr.
For example, with this PR, the current Zephyr SDK is 0.11.1 but when
releasing 0.12 then the current Zephyr will no longer built.
This PR moves the Zephyr SDK CMake related code to the SDK and thus
allowing to use newer SDKs, as long as they are backwards compatible.
It also allows multiple SDK installations, and will automatically select
the version closet to the required version.
