Tidy up ACPI ID table:
- drop ACPI_PTR() and hence replace acpi.h with mod_devicetable.h et al.
- drop comma in the terminator entry
With that done, extend compile test coverage.

Switch to use dev_err_probe() to simplify the error path and
unify a message template.

There are serial_port_in()/serial_port_out() helpers to be used
instead of direct p->serial_in()/p->serial_out().
Use them in various 8250 drivers.

It doesn't matter if the properties are supplied or not in
the struct ni16550_device_info as default in any case is 0.
Hence there is no need to check for them being set.

UPF_IOREMAP is for serial core to map the resource on behalf of the
driver. No need to perform this explicitly in the driver.

Since we have now a common helper to read port properties
use it instead of sparse home grown solution.

The National Instruments (NI) 16550 is a 16550-like UART with larger
FIFOs and embedded RS-232/RS-485 transceiver control circuitry. This
patch adds a driver that can operate this UART, which is used for
onboard serial ports in several NI embedded controller designs.
Portions of this driver were originally written by Jaeden Amero and
Karthik Manamcheri, with extensive cleanups and refactors since by
Brenda Streiff.
