Adds a shim layer around the mcux lpi2c driver to adapt it to the zephyr
i2c interface. This shim driver leverages heavily from the mcux i2c shim
driver because the MCUXpresso SDK provides similar APIs for the i2c and
lpi2c peripherals.

The SimpleLink wifi driver enables the Fast Connect method of
WiFi provisioning, which allows the network coprocessor to
reconnect to a previously connected Access Point (AP) on
startup.
Previously, if Fast Connect failed to connect, any network
socket applications would inevitably fail, as there would have
been no wifi connection.
This patch adds a configurable timeout for the Fast Connect
feature, after which timeout, an error is logged informing
the user to manually reconnect to an AP.
Reconnection is typically accomplished by separately running the
wifi sample shell program.

Commit aad21ecb31 introduced an incorrect
pattern of handling ADC sampling requests with invalid parameters in
both nRF ADC drivers. After discarding such request, the drivers do not
release properly the access lock and therefore become unusable.
Unfortunately, this pattern were later on copied in all other ADC
drivers in the source tree.
This commit adds the proper lock releasing in all the affected drivers.

net_buf_linearize() used to clear the contents of output buffer,
just to fill it with data as the next step. The only effect that
would have is if less data was written to the output buffer. But
it's not reliable for a caller to rely on net_buf_linearize() for
that, instead callers should take care to handle any conditions
like that themselves. For example, a caller which wants to process
the data as zero-terminated string, must reserve a byte for it
in the output buffer explicitly (and set it to zero).
The only in-tree user which relied on clearing output buffer was
wncm14a2a.c. But either had buffer sizes calculated very precisely
to always accommodate extra trailing zero byte (without providing
code comments about this), or arguably could suffer from buffer
overruns (at least if data received from a modem was invalid and
filled up all destination buffer, leaving no space for trailing
zero).

This patch adds a x86_64 architecture and qemu_x86_64 board to Zephyr.
Only the basic architecture support needed to run 64 bit code is
added; no drivers are added, though a low-level console exists and is
wired to printk().
The support is built on top of a "X86 underkernel" layer, which can be
built in isolation as a unit test on a Linux host.
Limitations:
+ Right now the SDK lacks an x86_64 toolchain. The build will fall
back to a host toolchain if it finds no cross compiler defined,
which is tested to work on gcc 8.2.1 right now.
+ No x87/SSE/AVX usage is allowed. This is a stronger limitation than
other architectures where the instructions work from one thread even
if the context switch code doesn't support it. We are passing
-no-sse to prevent gcc from automatically generating SSE
instructions for non-floating-point purposes, which has the side
effect of changing the ABI. Future work to handle the FPU registers
will need to be combined with an "application" ABI distinct from the
kernel one (or just to require USERSPACE).
+ Paging is enabled (it has to be in long mode), but is a 1:1 mapping
of all memory. No MMU/USERSPACE support yet.
+ We are building with -mno-red-zone for stack size reasons, but this
is a valuable optimization. Enabling it requires automatic stack
switching, which requires a TSS, which means it has to happen after
MMU support.
+ The OS runs in 64 bit mode, but for compatibility reasons is
compiled to the 32 bit "X32" ABI. So while the full 64 bit
registers and instruction set are available, C pointers are 32 bits
long and Zephyr is constrained to run in the bottom 4G of memory.

The HPET default is to deliver events on the same INTIn as the legacy
PIT IRQ, and in fact our code requires that because it uses the
"legacy routing" option. So this isn't really a configurable and has
to be set correctly. Do it right in the kconfig default instead of
forcing boards to set it.

Functions of control GPIO of these series scattered in
soc/arm/st_stm32/stm32xx/ folders contain these functions:
stm32_gpio_flags_to_conf(), stm32_gpio_configure(), stm32_gpio_set(),
stm32_gpio_get, stm32_gpio_enable_int().
This patch merges them into the gpio_stm32.c file.
