For DWC_GMAC_ALT_DESC implementations, the multicast hash table has only
64 entries. Instead of 8 registers starting at 0x500, a pair of registers
at 0x08 and 0x0c are used instead.

No functional change, only trivial cases are done in this sweep,
Drivers that can get further enhancements will be done independently.

This also adds a newbus interface that allows a SoC to override the
following settings:
- if_dwc specific SoC initialization;
- if_dwc descriptor type;
- if_dwc MII clock.
This seems to be an old version of the hardware descriptors but it is
still in use in a few SoCs (namely Allwinner A20 and Amlogic at least).
Tested on Cubieboard2 and Banana pi.
Tested for regressions on Altera Cyclone by br@ (old version).

Previously the OACTIVE flag was being set when the tx descriptors are fully
allocated but it wasn't unset anywhere.
As soon as a packet is transmitted, unset the OACTIVE flag and call start
routine to push any pending packets from the tx queue.
This closes another race where a full tx queue would jam the tx path (tx
queue is full, new packets cannot be added to queue and dwc_txstart never
gets called).
