The error handling in recv() is somewhat broken, for instance
good_packet isn't really used, and it's hardly readable. Also we try
to check for short or too big packets, but those are actually filtered
out by the hardware.
Simplify the whole routine and improve the error handling:
- Bail out early if the current RX descriptor is not ready.
- Enable propagation of runt, huge and broken packets.
- Check for runt and huge packets, and return 0 to indicate this.
This will force the framework to call free_pkt for cleanup.
- Avoid aligning the packet buffer for invalidation again.

The EMAC soft reset routine was subtly broken, using an open coded

Remove the unneeded initial reset bit read, and call wait_for_bit_le32()

To meet the current alignment requirements for our cache maintenance
functions, we were explicitly aligning the *arguments* to those calls.
This is not only ugly to read, but also wrong, as we need to make sure
we are not accidentally stepping on other data.
Provide wrapper functions for the common case of cleaning or
invalidating a descriptor, to make the cache maintenance calls more
readable. This fixes a good deal of the problematic calls.

However we tell the MAC about the beginning of the chain, so we have to

When initialising the TX DMA descriptors, we mostly chain them up,
but of course don't know about any data or its length yet.
That means they are still invalid, and the OWN bit should NOT be set
yet.
In fact when we later tell the MAC about the beginning of the chain,
and enable TX DMA in the start() routine, the MAC will start fetching
TX descriptors prematurely, as it can be seen by dumping the TX_DMA_STA
and TX_DMA_CUR_DESC registers.
Clear the owner bit, to not give the MAC the wrong illusion that it
owns the descriptors already.

With DM enabled the ethernet code will receive a packet, call
the push method that's set by the EFI network implementation
and then free the packet. Unfortunately the push methods only
sets a flag that the packet needs to be handled, but the code
that provides the packet to an EFI application runs after the
packet has already been freed.
To rectify this issue, adjust the push method to accept the packet
and store it in a temporary buffer. The EFI application then gets
the data copied from that buffer. This way the packet is cached
until is is needed.
The DM Ethernet stack tries to receive 32 packets at once, thus
we better allocate as many buffers as the stack.
