Log message:
Move the cpu_setup() call to the end of initarm(). On Cortex-A53 processors
atomic instructions don't work unless the data cache is enabled. This happens
in cpu_setup(), but that gets currently called from cpu_startup() which runs
after a number of kernel subsystems have been initialized. Since some of
these subsystems use locks, which need atomic instructions, we fault on
Cortex-A53. Since at the end of initarm() we're done setting up the pmap
and initializing other low-level sense, calling cpu_setup() here makes much
more sense.
Remove setting up proc0paddr as well from cpu_startup(), since that already
happens in initarm().
