p54spi: update sample eeprom

Commit: "p54: enhance rssi->dBm database import"
changed the way how the driver deals with the
rssical data. A new data format was necessary
and hence this patch.

NOTE: (for users with a custom eeprom binary)
I spent some time updating p54tools to support
the new format too: => (git available from)
http://git.kernel.org/?p=linux/kernel/git/chr/p54tools.git

It now comes with a simplistic script "n800_rssi2v2.sh"
which can be used to automate the conversion.
