Tested on Asurada Spherion Chromebook as well. In particular, verified that
applying this commit makes suspend/resume work. Before, it would hang during
resume:

	Enabling non-boot CPUs ...
	Detected VIPT I-cache on CPU1
	GICv3: CPU1: found redistributor 100 region 0:0x000000000c060000
	CPU1: Booted secondary processor 0x0000000100 [0x412fd050]

But with this commit applied the machine is able to proceed bringing up the
secondary processors and complete resume.

Thanks,
Nícolas
