ACPI: remove duplicated lines of merging problems with acpi_processor_start

When checking driver-core tree, found crazying warnings on my setups.

It turns out acpi_processor_power_init() get called two time in acpi_processor_add and acpi_processor_start.

Found several lines are duplicated in those two functions even related commit move them.

The related patches are ok. Not sure how it could happen, looks like git problem.

Those lines have two copies.

Looks more like somebody just applied the same patch twice, or just cut-and-pasted a few too many times.
