Fastsleep is one of the idle state which cpuidle subsystem currently
uses on power8 machines. In this state L2 cache is brought down to a
threshold voltage. Therefore when the core is in fastsleep, the
communication between L2 and L3 needs to be fenced. But there is a bug
in the current power8 chip
This is a cleanup patch; doesn't change any functionality. Moves
all cpuidle related code from setup.c to a new file.

Currently we print "Starting Linux PPC64" at boot. But we don't mention
anywhere whether the kernel is big or little endian.
If we print the utsname->machine value instead we get either "ppc64" or
"ppc64le" which is much more informative, eg:
