[PATCH v3 7/8] sparc/sun4m: Use start-powered-off CPUState property

[Thiago Jung Bauermann <bauerman@linux.ibm.com>]

Instead of setting CPUState::halted to 1 in secondary_cpu_reset(), use the
start-powered-off property which makes cpu_common_reset() initialize it
to 1 in common code.

This makes secondary_cpu_reset() unnecessary, so remove it.

Also remove setting of cs->halted from cpu_devinit(), which seems out of
place when compared to similar code in other architectures (e.g.,
ppce500_init() in hw/ppc/e500.c).
