Reenable PCI on DBAU1500. May still be useful for PIO devices. Comments

Add a PMAP-driven bus_space for access to upper memory, instead of using
wired entries.
Convert aupci to use said bus_space -- no measured performance impact.

Add a bus_space that makes use of wired TLB entries, as required for PCI,
PCMCIA, and perhaps other devices on Alchemy parts.

Reviewed as part of PCI changes by matt@, izumi@, and probably also simonb@.

This implementation has been tested seperately with my PCI code. This commit
does not add the necessary changes to configuration files to include this in
current configurations yet, as I intend to add that when I add the
multi-platform configuration support for evbmips/alchemy (which will be
required for PCI anyway.)

#include <sys/bus.h> instead of <machine/bus.h>.

Add an option COM_REGMAP to allow com(4) to use an array of register indices.
This allows us to convert aucom to just another com attachment, and cleanup
some code in the com_arbus.c.

Additionally, we use a common com_cleanup routine rather than having a
zillion copies of it in the attachment points.

This has been tested on a number architectures, and it has been shown to get
close to comparable performance when COM_REGMAP is defined, and comparable
when it is not defined.

Approved by core@. Fixes PR port-evbmips/32362.

Add support for the the Alchemy Semiconductor Au1x00 series on-chip
devices. Currently the serial ports and ethernet MAC have working
drivers, and this has only been physically tested on the Au1000 CPU,
but these devices should work on the Au1100 and Au1500 CPUs too.

fix various typos, mainly in comments, but also log messages, docs, game text.

Fix base-address for PSC devices.

Add Au1XXX PSC(Programable Serial Controller) bus-type driver.
PSC supports four protocols (AC97, I2S, SPI, SMBus).
These protocol drivers will be configured on the bus.

Add missing GPIO_BASE, plus clean up PCMCIA_BASE and add STATIC_BUS_BASE.
Fixes build error noted by martin@

Reduce address space used by PCI.
Add definitions for PCMCIA addresses.

Split out peripheral register defines from aureg.h. As discussed with
simonb@.

Remove if_aumac register defs, which were generally #ifdef'd out anyway.

Remove not-useful UART references from aureg.h, duplicates consolidated into
aucomreg.h. First part of aureg.h cleanup requested by simonb@.

Add Au1550 PCI support (Au1500 not yet, coming shortly).

Add au_intr_enable() and au_intr_disable() API to allow for split interrupts
(e.g. PCMCIA leaves GPIO interrupt masked and reenables them soft interrupt.)
Add checks for masked interrupts before calling the handler.
When removing last interrupt handler, mask off interrupts completely using
MASK_CLEAR and WAKEUP_CLEAR. Tested on dbau1500.
