Moved the definitions of the bits in the ns*50 registers from sioreg.h
to ns16550.h. The organization of these files was sort of backwards.
The bits in the registers have no driver or bus dependencies but they
but the offsets of the registers in bus space are very bus-dependent.
However, it does no harm to keep the definitions of the register offsets
in ns16550.h provided they are thought of as internal ns*50 offsets.

Move the com_emr register definition to sioreg.h.

Make the speed used by gdb over serial settable in the kernel configuration.

This facilitates the use in circumstances where you are using a serial
console as well. GDB doesn't support anything higher than 9600 baud (19k2
if you are lucky), but the console does.

Remove obsolete COMBRD* definitions.

Add support for different serial clock frequencies and not just the
standard one of 1.8432MHz. This will be used by the puc (PCI
"universal" communication card) device driver.

Break out the bus front ends into their own files. Rewrite
sio_pccard_detach to use new siodetach. Add an extra arg to sioprobe
to tell driver to probe/not probe the device for IRQs.

This incorporates most of Bruce's review material. I'm at a good
checkpoint, but there will be more to come based on bde's further
reviews.

Restore the old sio* - bruce can fix it himself.
