Initially I had to write to both the MASK and ENABLE registers, otherwise
the CPLD would generate tons of spurious interrupts. With the change to
the demux handler to disable the muxed line, it is now sufficient to
disable the interrupt by writing either the enable or mask register.

No test hardware and no (apparent) users. These boards seem very
similar to the DB1500, so if required support can be brought back
again (I have datasheets) but then with dedicated board code, not
tacked on to DB1000 support.

Now that no driver any longer depends on the CONFIG_SOC_AU1??? symbols,
it's time to get rid of them: Move some of the platform devices to the
boards which can use them, Rename a few (unused) constants in the header,
Replace them with MIPS_ALCHEMY in the various Kconfig files. Finally
delete them altogether from the Alchemy Kconfig file.

This patch removes the last hardcoded base address from the au1000_eth
driver. The base address of the MACDMA unit was derived from the
platform device id; if someone registered the MACs in inverse order
both would not work.
So instead pass the base address of the DMA unit to the driver with
the other platform resource information.

This also fixes a bug in the mtx-1_wdt driver which was introduced by
commit 6ea8115bb6
("Convert mtx1 wdt to be a platform device and use generic GPIO API")
before this patch mtx-1_wdt only modified GPIO215, the patch then
used the gpio resource information as bit index into the GPIO2 register
but the conversion to the GPIO API didn't realize that.
With this patch the drivers original behaviour is restored and GPIO15
is left alone.

The code called set_irq_chip_and_handler_name() resp. set_irq_chip()

__irq_set_chip_handler_name_locked() avoids that.

Since commit 32fd6901 (MIPS: Alchemy: get rid of common/reset.c)
Alchemy-based boards use their own reset function. For MTX-1 and XXS1500,
the reset function pokes at the BCSR.SYSTEM_RESET register, but this does
not work. According to Bruno Randolf, this was not tested when written.
Previously, the generic au1000_restart() routine called the board specific
reset function, which for MTX-1 and XXS1500 did not work, but finally made
a jump to the reset vector, which really triggers a system restart. Fix
reboot for both targets by jumping to the reset vector.

When au1000_eth probes the MII bus for PHY address, if we do not set
au1000_eth platform data's phy_search_highest_address, the MII probing
logic will exit early and will assume a valid PHY is found at address 0.
For MTX-1, the PHY is at address 31, and without this patch, the link
detection/speed/duplex would not work correctly.
