The 88f6192 and 88f6281 Kirkwood SoCs support two ethernet ports.
Add the platform glue that will allow board support files to
instantiate the second ethernet port.

When ISA_DMA_API is unset, we're not implementing the ISA DMA API,
so there's no point in publishing the prototypes via asm/dma.h, nor
including the machine dependent parts of that API.
This allows us to remove a lot of mach/dma.h files which don't contain
any useful code. Unfortunately though, some platforms put their own
private non-ISA definitions into mach/dma.h, so we leave these behind
and fix the appropriate #include statments.

Let's provide an overridable default instead of having every machine
class define __virt_to_bus and __bus_to_virt to the same thing. What
most platforms are using is bus_addr == phys_addr so such is the default.
One exception is ebsa110 which has no DMA what so ever, so the actual
definition is not important except only for proper compilation. Also
added a comment about the special footbridge bus translation.
Let's also remove comments alluding to set_dma_addr which is not
(and should not) be commonly used.

Add support to the Kirkwood port for newer device models and silicon
revisions. Instead of looking at the DEVICE_ID register, the device
version is now determined by looking at the PCI-Express device ID and
revision registers, as it is done for orion5x, and this information
is used to determine the TCLK frequency, again, as it is done for
orion5x.

Currently, kirkwood uses a hardcoded timer tick rate of 166 MHz, but
the actual timer tick rate varies between different members of the SoC
family.
This patch prepares for runtime determination of the timer tick rate.

Wire up the ethernet port's error interrupt so that the
mv643xx_eth driver can sleep for SMI event completion instead of
having to busy-wait for it.
