[U-Boot] [PATCH] ARM: kirkwood: add spi0 alias for dreamplug

[Chris Packham]

The conversion to DM_SPI managed to break accessing the environment on
dreamplug. This is because the environment code relies on being to able
to select the SPI device based on the sequence number. Add an alias so
that the spi0 bus gets sequence number 0.

Leigh,

Could you test this on your system for me. I'm only able to compile test
this myself.
