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
detail.

Commit 58c8d15 ("clock control:stm32: provide STM32Cube LL based
driver") added PLL initialization which disables the PLL before
configuring it.
This works if the system clock source is not the PLL (which is the
usual case for Zephyr booting out of chip reset). However, if the
SYSCLK source *is* the PLL, this halts execution.
To support this use case, switch the SYSCLK source to the
always-present HSI before disabling the PLL.

The main difference to how the previous driver operates, is that this
version has zero-copy transmission. The transmit DMA descriptor is
updated for every fragment that is transmitted from the driver.
Another difference in the transmission path is that this version won't
spin indefinitely while waiting for the DMA transfer to complete; an
arbitrary number of busy checks (20) will be performed, and then
the transmission thread will yield for as long as necessary to finish
the transfer.
These two changes should fix ZEP-472; since that issue was opened for
an older version of Zephyr with uIP, I did not bother going all the way
back to test.
This has been only tested with a Galileo board, using Shared IRQ.

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).
