sun4u: ebus QOMify tidy-up

Browse Source 
The main change here is to introduce the proper TYPE_EBUS/EBUS QOM macros
and remove the use of DO_UPCAST.

Alongside this there are some a couple of minor cosmetic changes and a rename
of pci_ebus_realize() to ebus_realize() since the ebus device is always what
is effectively a PCI-ISA bridge.
