[parisc-linux] Revised PA-RISC 1.1 Documentation

[Christopher Beard]

Just noticed that the PA-RISC 1.1 Instruction Set Architecture
documentation webpage has been cleaned up. There are also now links to the
.pdf versions.

I don't know how new this is, but I recall looking for these before and
the page being quite outdated. I'll post this to the project web page as
well.
