Two DMA channels are assigned to TX and RX respectively:
- A TX DMA request is asserted when there is space in the FIFO.
- A RX DMA request is asserted when data is in the FIFO.
When DMA is enabled for a peripheral, the DMA transfer completion is
signaled on the peripheral's interrupt only (here UART's interrupt).
It is not signaled on the DMA dedicated interrupt.
Also, when DMA is enabled for a peripheral, the DMA controller stops
the normal transfer interrupts for this peripheral from reaching the
NVIC (the interrupts are still reported in the interrupt registers of
the peripheral). Thus, when a large amount of data is transferred using
DMA, instead of receiving multiple interrupts from the peripheral as
data flows, the NVIC receives only one interrupt when the transfer
completes (unmasked peripheral error interrupts continue to be sent
to the NVIC).

Add a reusable uart-bridge driver that echoes data between two serial
devices. It's mainly meant to be used with one of the devices being an
USB CDC-ACM, the data is buffered, there's a pause feature to stop the
USB endpoint when the hardware UART is filling up to avoid overrun and
there's a helper function used to propagate the USB uart configuration
to the hardware one.

Rename the driver from uart_native_posix to uart_native_pty.
Including renaming the DTS compatible, and kconfig options, deprecating
the old ones.
And refactor the driver, generalizing it, so we can have any number of
instances.
Note that, unfortunately generalizing to N instances cannot be done
without a degree of backwards compatibility breakage: This driver was
born with all its configuration and selection of the instances based on
kconfig.
When the driver was made to use DT, it was done in a way that required
both DT and kconfig needing to manually coherently enable the 2nd UART.
This has now been fixed, which it means only DT is used to decide how
many instances are avaliable, and UART_NATIVE_POSIX_PORT_1_ENABLE is
just ignored.
Including:
* Deprecate UART_NATIVE_WAIT_PTS_READY_ENABLE: the options is always on
now as it has no practical drawbacks.
* Deprecate UART_NATIVE_POSIX_PORT_1_ENABLE: DTS intanciation defines it
being available now.
* Rename a few functions and in general shorten pseudo-tty/pseudo-
terminal to PTY instead of PTTY.

The Atmel SAM0 SoC enable peripherals clocks in distinct places: PM and
MCLK. The old devices had defined the peripheral clock enable bit at PM.
On the newer devices this was extracted on a dedicated memory section
called Master Clock (MCLK). This change excludes the dedicated bindings
in favor of a generic approach that cover all cases.
Now the clocks properties is complemented by the atmel,assigned-clocks
property. It gives the liberty to user to customize the clock source
from a generic clock or configure the direct connections.
All peripherals drivers were reworked with the newer solution.
