mount: add compatibility to old mount command ...

the mount command used to have the syntax 'mount <dev> <type> <mountpoint>'.
This was changed to the more Linux like behaviour which specifies the
type with the -t <type> option. If a newer barebox is run on a device
with an older environment the mount command no longer works. This patch
adds compatibility to the old behaviour.

bootm: Do not cross 1MiB sections for the devicetree ...

ARM Linux only maps a single 1MiB section for the devicetree. This has
a 1Mib alignment, so we are not allowed to cross such a boundary. Align
the devicetree to the next power of two so that this never happens.

bootm: Add a define for the additional devicetree size ...

The fixed devicetree may need more space than the original one.
We used to use 0x8000 here. Add a define for it to have the
space defined at a single place.

commands: Add clk commands ...

This adds some basic commands to manupulate clocks on the command
line. Right now we have:

- clk_set_parent
- clk_set_rate
- clk_enable
- clk_disable
- clk_dump

The commands work based on the clock name, otherwise they behave like
the Linux Kernel C functions. clk_dump will dump the clocktree to the
console.

net: Add tftp command which uses the new tftp code ...

Traditionally tftp is a command of its own. Since we can
mount tftp as a filesystem we have duplicated the tftp code, the old
code is used by the tftp command, the new by the filesystem support.
This adds a tftp command based on the filesystem support to preserve
backward compatibility. This allows us to remove the old tftp support
in the next step.

With this the -p option is no longer for parse, but for probe instead.
Using this parses a devicetree given on the command line and probes

probed again, but instead their device_node is attached to the existing
device.
