This fixes two bugs.
First a fix from Daniel Hellstrom that eliminates a hard-coded HZ
constant in the LEON code.
Second, fix a regression in sparc64 firmware calls.
Some kinds of firmware calls are not safe to pass buffer addresses
over 4GB, they really aren't 64-bit safe universally especially on
older sparc64 systems.
So I fixed this in two steps:
1) Remove firmware interfaces unused by the kernel right now, which is
safer than trying to recode them to use bounce buffers or similar.
2) Add a bounce buffer for PROM console writes to ensure that the
buffer restrictions are met.
Tested successfully by the original bug reporter.
Please pull, thanks a lot!
