The registration of each serial port differs only by a few details.
These differences can be factorized in order to create a generic
registration macro.
This has several advantages:
- Less code
- Easier to add new ports
- Less work to add support for new STM32 families

uart_irq_tx_empty() function proved to be problematic: its semantics
was not documented properly, and many hardware uses terminology like
"TX register empty" to signify condition of TX register being ready
to accept another character (what in Zephyr is tested with
uart_irq_tx_ready()). To avoid confusion, uart_irq_tx_empty() was
renamed to uart_irq_tx_complete(), propagating to drivers/serial
device methods.
The semantics and usage model of all of uart_irq_rx_ready(),
uart_irq_tx_ready(), uart_irq_tx_complete() is now described in

The purpose of irq_update() is to cache value of UART IRQ status
register for devices which needs such caching. No other driver
performs any other side effects in this call. For STM32, clearing
TC (tx complete) bit was introduced in 8c079e91c9
which is otherwise titled as a conversion to STM32Cube HAL. Thus,
there does not seem to be specific reasons why this code was added.
On the other hand, it leads to behaviorial artifacts when dealing
with interrup-driven UART code (specific issue seen was delaying
of transmitting every other character).

Don't busy-wait in uart_stm32_fifo_fill(), this routine is supposed
to be called on IRQ, and the waiting loop was shown to interfere
with interrupt-driven UART handling.
The original problem mentioned in the patch being reverted ("it is
possible to evaluate the TXE bit *before* H/W has had the
opportunity to detect that data is being processed") may still
exist and may require handling in a different way. The most obvious
way is to replace "while" loop with "if", because STM32 doesn't
have multi-level FIFO anyway. But I was dissuaded to include such a
change as part of this patch, so it's left for future analysis.
This reverts commit 49c2858d94.

We introduce <zephyr/types.h> as part of this and have it include

types.
We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some

Adds a shim layer around the mcux lpuart driver to adapt it to the Zephyr
serial interface.
NXP has multiple uart hardware blocks that implement different features
and have different register maps. The k64 has a uart block called
'uart', while the kw41 has a uart block called 'lpuart' (low power
uart). The MCUXpresso SDK provides separate drivers for each type of
uart block but with similar software interfaces. As a result, there are
also separate shim drivers in Zephyr. There is a 1:1:1 relationship
between hardware block, mcux driver, and mcux shim driver.
Because we now have two mcux shim drivers for the uart interface, a new
naming convention is created:
<interface>_mcux_<hw block>
Where <interface> is the name of the Zephyr interface, in this case
'uart'. This convention is not new.
<hw block> is the name of the NXP hardware block, in this case 'lpuart'.
This is the new part, and distinguishes different hardware blocks
for the same interface.
