66bb831f44 gpu: nvgpu: Register as subdomain of host1x
Add gk20a as a sub power domain of host1x. This enforces keeping
host1x on when using gk20a.

d224ca2008 gpu: nvgpu: Get host1x device from DTS
Currently the gpu driver assumes that the GPU is a child of host1x.
This is an invalid assumption and therefore we need to get the host1x
device from device tree based on nvidia,host1x property.

efad6452f6 gpu: nvgpu: handle error when gpu failed to unpowergate
After flash, kernel needs to reboot after first boot.
During reboot, devices is going to be shutdown including i2c.
But sometimes gpu driver trys to open gpu sysfs nodes and
unpowergate gpu at the same time. But i2c is already shutdown.
tegra_unpowergate_partition returns error in this case but
gk20a_tegra_unrailgate did not report the error so the error
is not handled. Return proper value in gk20a_tegra_unrailgate
to avoid this.
