powerpc/chrp: Use the same RTAS daemon as pSeries
The CHRP code has some fishy timer based code to scan the RTAS event
log, which uses a 1KB stack buffer and doesn't even use the results.
The pSeries code as a nicer daemon that allows userspace to read the
event log and basically uses the same RTAS interface
This patch moves rtasd.c out of platform/pseries and makes it usable
by CHRP, after removing the old crufty event log mechanism in there.
The nvram logging part of the daemon is still only available on 64-bit
since the underlying nvram management routines aren't currently shared.
