Convert driver to use new DT_INST macros throughout. Removed per

Make I2C and SPI drivers for nRF SoCs no longer dependent on Kconfig
options that enable instances (i.e. I2C_x and SPI_x). Now these drivers
enable hardware instances when corresponding nodes in devicetree are
enabled (have status "okay").
For I2C, SPI, and UART drivers, instead of using Kconfig dependencies
to prevent enabling of hardware instances that cannot be used together
(e.g. SPIM1 and TWIM1), a file that signals invalid configurations with
build assertions is added to compilation.
Also dependencies on HAS_HW_NRF_* options are removed from Kconfigs
of I2C, SPI, and UART drivers, as for hidden options that activate
proper type of driver such dependencies are not actually helpful.

Remove prompts from Kconfig options `UART_x_NRF_UART*` that select
the type of nrfx driver (for UART or UARTE peripheral) to be used
for a given instance. This prevents the options from being modified
from configuration files.
Instead, make one of these options selected by default according to the
"compatible" property set for the corresponding UART node in devicetree.
This eliminates the need of changing both the "compatible" property in
devicetree and the Kconfig option selecting the driver type when a user
wants to switch between UART and UARTE for a given instance.
Since all `UART_x_NRF_UART*` options are made "hidden" by this commit,
all their occurrences in configuration files are removed.

Convert older DT_INST_ macro use in arm_cmsdk/arm drivers to the new
include/devicetree.h DT_INST macro APIs.

Add a k_timeout_t type, and use it everywhere that kernel API
functions were accepting a millisecond timeout argument. Instead of
forcing milliseconds everywhere (which are often not integrally
representable as system ticks), do the conversion to ticks at the
point where the timeout is created. This avoids an extra unit
conversion in some application code, and allows us to express the
timeout in units other than milliseconds to achieve greater precision.
The existing K_MSEC() et. al. macros now return initializers for a
k_timeout_t.
The K_NO_WAIT and K_FOREVER constants have now become k_timeout_t
values, which means they cannot be operated on as integers.
Applications which have their own APIs that need to inspect these
vs. user-provided timeouts can now use a K_TIMEOUT_EQ() predicate to
test for equality.
Timer drivers, which receive an integer tick count in ther
z_clock_set_timeout() functions, now use the integer-valued
K_TICKS_FOREVER constant instead of K_FOREVER.
For the initial release, to preserve source compatibility, a
CONFIG_LEGACY_TIMEOUT_API kconfig is provided. When true, the
k_timeout_t will remain a compatible 32 bit value that will work with
any legacy Zephyr application.
Some subsystems present timeout (or timeout-like) values to their own
users as APIs that would re-use the kernel's own constants and
conventions. These will require some minor design work to adapt to
the new scheme (in most cases just using k_timeout_t directly in their
own API), and they have not been changed in this patch, instead
selecting CONFIG_LEGACY_TIMEOUT_API via kconfig. These subsystems
include: CAN Bus, the Microbit display driver, I2S, LoRa modem
drivers, the UART Async API, Video hardware drivers, the console
subsystem, and the network buffer abstraction.
k_sleep() now takes a k_timeout_t argument, with a k_msleep() variant
provided that works identically to the original API.
Most of the changes here are just type/configuration management and
documentation, but there are logic changes in mempool, where a loop
that used a timeout numerically has been reworked using a new
z_timeout_end_calc() predicate. Also in queue.c, a (when POLL was
enabled) a similar loop was needlessly used to try to retry the
k_poll() call after a spurious failure. But k_poll() does not fail
spuriously, so the loop was removed.

Kernel timeouts have always been a 32 bit integer despite the
existence of generation macros, and existing code has been
inconsistent about using them. Upcoming commits are going to make the
timeout arguments opaque, so fix things up to be rigorously correct.
Changes include:
+ Adding a K_TIMEOUT_EQ() macro for code that needs to compare timeout
values for equality (e.g. with K_FOREVER or K_NO_WAIT).
+ Adding a k_msleep() synonym for k_sleep() which can continue to take
integral arguments as k_sleep() moves away to timeout arguments.
+ Pervasively using the K_MSEC(), K_SECONDS(), et. al. macros to
generate timeout arguments.
+ Removing the usage of K_NO_WAIT as the final argument to
K_THREAD_DEFINE(). This is just a count of milliseconds and we need
to use a zero.
This patch include no logic changes and should not affect generated
code at all.
