com(4): Add include guards.

Simplify regmap initialization, and fix an regmap issue that
affected TI OMAP (LCR register would get clobbered due to
using the wrong offset for the MDR1 register) reported by Lwazi Dube
(who also found the root cause).

update from HEAD

Make all of the COM_xxx type options runtime selectable. Kernel configs
with the existing options (COM_16650, COM_16750, COM_AWIN, COM_HAYESP, and
COM_PXA2X0) will select the correct type in com_attach_subr. New code
should specify the com type by passing COM_TYPE_xxx to comcnattach and/or
setting sc_type.

The UART in the allwiner SoCs is not full-compatible with the 16550, and
it's not a 16750 either. Like the 16750 it has the IIR_BUSY interrupt,
which is triggered when writing to LCR while the chip
can't accept it. But unlike the 16750, it has a specific register,
HALT, to allow writing to the LCR and divisor registers, and then
commit the changes.
Tested on an A20 SoC, changing the baud rate while keeping the
tty device open and incoming data.

Revirt 'Move the Marvell extension to com_mv.c' at Sun Sep 1 04:51:24 UTC 2013.
  build test only.

Move the Marvell extension to com_mv.c.

resync from head

Add support for 16750 style UARTs. Activated by defining COM_16750.

Obtained from Marvell, Semihalf.

merge ktrace-lwp.

Fix the sync with head I botched.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

Whitespace glitch.

new RCS ID format.

Added com_scratch entry.

add rcsids to everything and clean up headers
