Now that we're clearer around pm constraints management in various
TX cases (poll streams, irq driven or async), make some code
simplifications to ease readability.

Introduce new logic to set/release pm_constraint during serial TX
transactions.
First change is to introduce an internal flag and utility functions
to control the set/release constraint balancing per uart device.
This way, whatever the mix of transactions or API calls, we
ensure a single uart device can only do 1 or 0 to the PM state
constraint. Constraint can't then be set more than once, released w/o
having been set or released more than it was set.
The last part of the change reworks the triggers for constraints
set/release operations.
In order not to disturb driver operations, if irq driven mode or PM is
enabled, don't enable TC interrupt handling by default.
Instead, map the pm_constraint setting to the way TC flag is handled
in normal mode of operations (irq driven or async).
As a consequence, in irq driven mode, pm_constraint is set/released on
tx_enable/tx_disable api calls, which gives API user full control
on transaction protection vs low power operations.
Finally, we emulate the same behavior on TX poll transaction, by
enabling TC irq at the start of a stream and disabling TC irq once
stream is completed. This is controlled with a dedicated device flag.

TWIM peripherals cannot perform write transactions from buffers
located in flash. The content of such buffers needs to be copied
to RAM before the actual transfer can be requested.
This commits adds a new property (zephyr,flash-buf-max-size) that
informs the driver how much space in RAM needs to be reserved for
such copying and adds proper handling of buffers located in flash.
This fixes an issue that caused that e.g. the DPS310 sensor driver
did not work on nRF SoCs that only have TWIM, not TWI peripherals.

Issue an error logging message when the i2c_nrfx_twim driver lacks
a concatenation buffer big enough to properly handle a call to
i2c_burst_write() function, to give the user a hint what is wrong.
Also use by default a 16-bytes long concatenation buffer for every
instance of the i2c_nrfx_twim driver. Such value should cover most
of the simple uses of the i2c_burst_write() function, like those
in the stmemsc sensor drivers, and when a longer buffer is needed,
the user will be provided with the above message pointing to the
property that should be adjusted.

In the current implementation the STM32 UART driver required to enable
`CONFIG_PM_DEVICE` when `CONFIG_PM=y` to function properly. The main
reason is that in some situations, like in polling mode, transmissions
are not fully synchronous. That is, a byte is pushed to the _queue_ if
it is empty and then the function returns without waiting for it to be
transmitted to the wire. This makes sense to make things like per-byte
transmission efficient. However, this introduces a problem: the system
may reach idle state, and so enter low power modes before the UART has
actually finished the last data in the queue. If this happens,
communications can be interrupted or garbage data may be put into the
UART line.
The proposed solution in this patch uses PM constraints to solve this
problem. For the IRQ/DMA case it is easy since we can set the constraint
before transmission start, and when the completion (TC) interrupt is
received we can clear it. However, the polling mode did not have the
capability to signal the completion. For this case, a simpler IRQ
routine is provided to just release the constraint. As a result, the PM
hooks are not required and so system can operate with just `CONFIG_PM`.

function even when BOOT_DELAY is enabled.
