We have several nearly identical default environments in the tree.
Lets merge them to a single environment and use it on many boards.
This defaultenv is arm centric at the moment due to the use of arm
specific boot commands. This can be improved over time.
changes since last version:
- fix potentially empty variable tests
- be a bit more verbose in boot script
- run a board specific init script (/env/bin/init_board) if it exists

Change device parameters so that the memory management is in generic
code. This also removes the need of storing statically initialized
parameters as they are stored in a struct list_head for each device.

The old network stack has some bad limitations:
- network commands are required to call NetLoop() which only returns when
the network layer wants to. Instead we now use a net_poll() function which
returns after handling one packet (or immediately if no packet is
available).
- There can be only one packet handler which makes it impossible to handle
multiple connections
- CamelCaseMakesItHardToRead
The new network stack is implemented as a parallel universe. Currently all
commands still use the old stack. They are converted in subsequent patches.

We used to eth_open/eth_halt the network devices during NetLoopInit
which is called whenever the user enters a network command.
Change this behaviour so that the current network device gets opened
when making it the current one.
With this change it's always possible to send packages and we are able
to implement a new network stack in the next step.

The fec network interface initialization depends on the initialization of the
PMIC. Once the MC34704 driver is registered we can enable the PHY power supply,
and go on with the PHY initialization.
While we are at it convert the hard-coded GPIO registers access to the general
GPIO API for shorter and clearer code.
