soc: rockchip: power-domain: avoid infinite loop
In some cases, we have met the infinite loop in
rockchip_pmu_set_idle_request() or rockchip_do_pmu_set_power_domain().
As the crosbug.com/p/57351 reported, the boot hangs right after this
[1.629163] bootconsole [uart8250] disabled
[1.639286] [drm:drm_core_init] Initialized drm 1.1.0 20060810
[1.645926] [drm:drm_get_platform_dev] Initialized vgem 1.0.0 20120112..

[1.660569] iommu: Adding device ff900000.vop to group 1
<hang>
This patch adds the error message and timeout to avoid infinite loop if
it fails to get the ack.
