parisc: Avoid printing the hardware path twice

commit 2b6ae0962b421103feb41a80406732944b0665b3 upstream.

Avoid that the hardware path is shown twice in the kernel log, and clean
up the output of the version numbers to show up in the same order as
they are listed in the hardware database in the hardware.c file.
Additionally, optimize the memory footprint of the hardware database
and mark some code as init code.
