Make getenv_IPaddr() global
There are boards out there that do not have network support in
U-Boot (CONFIG_CMD_NET not set), but they do so in Linux. This
makes it desirable to be able to port network configuration (like
the IP address) to the Linux kernel.
We should not make the passing of the IP configuration to Linux

For this, make getenv_IPaddr() global. This fixes build error

Support for LZARI compression mode was added based on a MTD CVS

As no boards ever used LZARI compression, and this file is also not

conflicting file and references to it.
Also copy the referenced but missing file 'LICENCE' from the current
