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.

This bug is awaiting verification that the linux-oem-6.5/6.5.0-1021.22 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy-linux-oem-6.5' to 'verification-done-jammy-linux-oem-6.5'. If the problem still exists, change the tag 'verification-needed-jammy-linux-oem-6.5' to 'verification-failed-jammy-linux-oem-6.5'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
