This API is not being used for anything, the interrupts for UART
drivers are all being configured statically. Saves code space as
gc-sections can't tell that these APIs are unused.
Some instances where IRQ/priority information was being saved in
data structures and never used fixed.

If we are not doing any dynamic interrupts or exceptions, we
can put the IDT in ROM and save a considerable amount of RAM,
up to 2K if the IDT is the default size of 256 entries.
The _interrupt_vectors_allocated table can also be put in ROM
if we're not using any dynamic interrupts.
We introduce a new Kconfig option to force the IDT to be in RAM
for situations where no dynamic IRQs are used, but ROM footprint
needs to be conserved.

Make the i2c_transfer() to transact messages through the I2C bus.
It is useful for I2C storage devices, as now we can send one message
containing the destination byte/block address, then send the data
in another message. There is no need to construct one continuous
data buffer to send both address and data anymore.
The drivers and sample apps have been updated to utilize updated
API when appropriate. For i2c_dw, only master mode has been updated.
Slave mode will be updated once we can adequately test it.

This patch introduces the infrastructure required to enable QMSI drivers.
QMSI drivers are shim drivers based on drivers provided by QMSI BSP. The
BSP provides a static library (libqmsi) which implements several drivers
for peripherals from Intel MCUs.
Next patch will introduce the first QMSI driver (watchdog driver) which
will rely on the infrastructure introduced by this patch.

Simplifies the nanokernel timer API so that the timeout parameter must be
specified when invoking nano_isr_timer_test(), nano_fiber_timer_test(),
nano_task_timer_test() and nano_timer_test().
This obsoletes the following APIs:
nano_fiber_timer_wait()
nano_task_timer_wait()
nano_timer_wait()
Note that even the though the new API requires that the timeout parameter
be specified, there are currentl only two acceptable values:
TICKS_NONE and TICKS_UNLIMITED
Theoretically, the current implementation would allow one to supply a
finite positive value for the timeout and the system would wait up to
that many ticks for the timer to expire. However, it is thought that
that unnecessarily complicates the nanokernel timer model and so it is
left as an unsupported option. Should that change, then that feature
could be enabled by updating the documentation.

The while loop on the status bit was unnecessary as we will get
a separate invocation of the ISR for every message. We also ensure
that the global status register bits for the channel being serviced
are cleared before exiting. Fixes an issue where some messages
would be dropped or repeated.
Some runtime checks that shouldn't happen in practice have been moved
to assertions.

This adds 2 new APIs to the serial/uart drivers:
() One is to control the serial line, such as RTS and CTS.
() Another one is to allow driver to expose hardware specific functions
to apps. This is needed as some hardware may have extra registers to
set for baud rate.
To keep the code size small, these features are disabled by default.
