add snps IP uart support / genaralize UART

This is an amalgam of a patch by Doug Ambrisko to
generalize uart_acpi_find_device, imp moving the
ACPI table to uart_dev_ns8250.c and advice by jhb
to work around a bug in the EPYC 3151 BIOS
(the BIOS incorrectly marks the serial ports as
disabled)

Restore alphabetical order in UART Makefile

Commit r323359 introduced new Marvell UART controller driver
and by mistake it broke correct order in the Makefile. Fix this.

Don't build uart_dev_mvebu unless we're on arm64.

This module is specific to a single Marvel board that we currently
only support in 64-bit mode. Remove it from the build otherwise. It
likely should be completely removed, but this unbreaks x86 building.

Kill MFILES and find things automatically. It turned out to be only
lightly used. Find the proper .m file when we depend on *_if.[ch] in
the srcs line, with seat-belts for false positive matches. This uses
make's path mechanism. A further refinement would be to calculate this
once, and then pass the resulting _MPATH to modules submakes.

PowerPC also needs ofw_bus_if.h when using FDT.

Fix the uart(4) module build. Without uart_dev_lpc the module cannot be loaded.

Use MACHINE_CPUARCH in preference to MACHINE_ARCH. The former is the

general, we want to use MACHINE_CPUARCH instead of MACHINE_ARCH unless
we're tesitng for a specific target. The isn't even moot for

In sun4v, use the sparc64 version. We haven't used the serial port on
sun4v yet, so this is a 'best-guess'.
