This patch adds support to expose eTSEC devices in the dynamically created
guest facing device tree. This allows us to expose eTSEC devices into guests
without changes in the machine file.
Because we can now tell the guest about eTSEC devices this patch allows the
user to sp
and map IRQs to predetermined IRQ lines that are reserved for platform
device usage.
This maps really nicely into device tree logic, so we can just tell the
guest about our virtual simple bus in device tree as well.

This patch allows the instantiation of the vfio-calxeda-xgmac device
from the QEMU command line (-device vfio-calxeda-xgmac,host="").
A specialized device tree node is created for the guest, containing
compat, dma-coherent, reg and interrupts properties.

The platform device class has become abstract. This patch introduces
a calxeda xgmac device that derives from it.

This patch adds the code requested to assign interrupts to
a guest. The interrupts are mediated through user handled
eventfds only.
The mechanics to start the IRQ handling is not yet there through.
