So far ESP chip was configured directly into STA mode. This works fine,
but consumes lots of power because of enabled WiFi radio, even when it
is not actively used.
Enter NONE mode during initialization, so WiFi radio will be
disabled. Switch between NONE, STA, AP and STA+AP modes depending on
what driver is currently doing (e.g. enable STA only when scanning,
connecting and being connected to AP).
AT+CWAUTOCONN=0 command fails when in NONE mode, so workaround that by
entering temporarily into STA and then switching back to NONE.
Add also a warning log when switching mode was not successful, to ease
debugging possible issues.

AT+CWMODE command controls in which mode (NONE, STA, AP, STA+AP) ESP
chip is operating. Add helper macros to replace usage of magic
numbers (0-3), hence improve readability. Add also a esp_mode_switch()
helper function, which allows to conveniently switch to chosen mode.

Command was sent first, then a semaphore was reset. This semaphore could
be released by received reply even before semaphore was reset. This is
quite unlikely, but possible result of race condition.
Move k_sem_reset() call before attempt to send command over modem
interface. This makes sure that receiving reply momentarily after
sending request will always be handled properly.

Semaphore argument is checked only after requested command is already
sent over modem interface. It makes little sense to return -EINVAL when
half of the requested operation (send) has already been done.
Check timeout and semaphore arguments just on the beginning of
function. Return -EINVAL early, before sending any data or taking any
locks.
Clear out 'sem' variable when there is no need to wait. Use this
variable later on as an indication to actually wait on semaphore or not.

When there is no data to send (e.g. i2c message with NULL buffer and
len=0), i2c_imx driver locks itself in isr handling forever.
So if there is no data to send, only device's address must be written
on bus. This fixes i2c_shell's scan command on both imx7 and imx6sx.

Added early return from uart_poll_out when uart device is not in
active state. Poll_out is used from many contexts by multiple users
and currently here is no mechanism in power management to disable
them (console, logger when going to inactive power state.
Additionally, moved setting new state when disactivating the device to
ensure that no poll_out will happen after disabling the UARTE.

This commit adds a new driver category for memory controller
peripherals. There is no API involved for now, as it has not been found
necessary for first implementation.
STM32 Flexible Memory Controller (FMC) is the only controller supported
for now. This peripheral allows to access multiple types of external
memories, e.g. SDRAM, NAND, NOR Flash...
The initial implementation adds support for the SDRAM controller only.
The HAL API is used, so the implementation should be portable to other
STM32 series. It has only been tested on H7 series, so for now it can
only be enabled when working on H7.
Linker facilities have also been added in order to allow applications to
easily define a variable in SDRAM.

Nothing in the API description the delayed work structure sanctions
direct reference to internal fields. Do not assume that a delayed
work item can be submitted without delay by invoking k_work_submit()
with a reference to the contained work item. Instead submit with the
delayed API and no wait.

Constifying global data allows to save lots of RAM. Defining data inside
function as 'static const' allows on the other hand to save stack usage
and reduced code size (because data doesn't have to be copied on stack
in runtime).
This improvement allows to save 448 bytes of RAM and 88 bytes of ROM
when compiled on ARM, with default configuration.
