This patch series adds a driver for the 16550-like UARTs on National
Instruments (NI) embedded controller hardware.

These UARTs have an interface that is compatble with the TL16C550C (for
which we build on top of 8250_core) but also has extra registers for
the embedded RS-232/RS-485 tranceiver control circuitry.

Changes from v3 -> v4:
- remove "clock-names" from schema, as there is only one clock
- remove legacy "clock-frequency" from schema
- use GENMASK
- fix spacing
- fix uartclk on NIC792B devices
- add comments to clarify flag usage

v3: https://lore.kernel.org/linux-serial/20230329154235.615349-1-brenda.streiff@ni.com/T/#me4a5f3dfe0282145565d409f06934739b7a4b023
