Add initial support for the Cortex-M55 Core which is an implementation
of the Armv8.1-M mainline architecture and includes support for the
M‑profile Vector Extension (MVE).
The support is based on the Cortex-M33 support that already exists in
Zephyr.

Resolution currently only gets set if CONFIG_MCP9808_TRIGGER is also
set. If CONFIG_MCP9808_TRIGGER is not set, resolution gets not to '0'.
This small bug fix moves resolution to before CONFIG_MCP9808_TRIGGER is
checked, so that the resolution is changed as required.

The clock/timer APIs are not application facing APIs, however, similar
to arch_ and a few other APIs they are available to implement drivers
and add support for new hardware and are documented and available to be
used outside of the clock/kernel subsystems.

writing a new timer driver to use.

When, due to EMC, a spike happens on the SCL line the driver stay in
BUSY state. It could be reproduced by forcing the SCL temporarily to
ground. It's probably a behavior relating to the operation of
multi-master.
By adding a timeout to the msg_read and msg_write function we can
detect that something went wrong, and when that happens we force the
end of communication.

Currently level interrupts are implemented using GPIO SENSE, but edge
interrupts using GPIOTE events. Using GPIOTE events results in increased
power consumption according to product specifications and erratas of
some nRF MCUs. In case of nRF52832 it is <20uA in System ON Idle and
~400-450uA when used in conjunction with SPI or TWI.
Add a user configurable option to select between GPIOTE events and GPIO
SENSE mechanism, for implementing edge interrupts. Selecting GPIO SENSE
option will allow to reduce power consumption in scenarios mentioned by
nRF MCUs erratas.
Additionally GPIO SENSE mechanism (as opposed to GPIOTE event) allows to
detect state changes of pins configured as output.

The fixed number of 24 RTEs is a legacy thing, and long gone by now.
IOAPICs expose the maximum number of RTEs they have via the version
register, so let's use it.

and fixes the RTE number for all x86 targets relevantly.

Autostarting PPP is far from controversial. There are many, many reasons
someone could have for wanting to control exactly when PPP starts. Power
management, NET_EVENT race condition avoidance and any application not
requiring constant and instant use of networking just to name a few.
This commit introduces a Kconfig setting, GSM_PPP_AUTOSTART, which
controls whether gsm_ppp should connect and initialize PPP at boot. It
is set to "y" as default to minimize surprises for legacy code.
