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 compatible with the TL16C550C (for
which we build on top of 8250_core) but also has extra registers for
the embedded RS-232/RS-485 transceiver control circuitry.

- fix unused-const-variable warnings with COMPILE_TEST=y and W=1
