Bug description:
[Impact]
i915 error can sometimes be found in kernel message when booting the machine
w/ power unplugged
kernel: i915 0000:00:02.0: [drm] *ERROR* GT1: GuC initialization failed -EIO
kernel: i915 0000:00:02.0: [drm] *ERROR* GT1: Enabling uc failed (-5)
kernel: i915 0000:00:02.0: [drm] *ERROR* GT1: Failed to initialize GPU,
declaring it wedged!
The GPU won't work with this failure
[Fix]
Backport the upatream fix for allowing slow HuC loading.
[Test]
1. Unplug the power of the laptop and make sure it's charged by battery
2. Cold boot or Warm boot the machine and check the GuC init fail message.
3. Go to settings - > about --> graphics to make sure the GPU information is
correct every boot.
[Where problems could occur]
Simply increase the loading time of HuC still get a working system. Should be
low risk of regression.
