[Why]
Intermittent reboot hangs are observed introduced by
"Improve x86 and dmub ips handshake".
[How]
Bring back the commit but fix the polling.
Avoid hanging in place forever by bounding the delay and ensure that
we still message DMCUB on IPS2 exit to notify driver idle has been
cleared.

[Why & How]
Currently set_default_brightness_aux function uses 5 nits as lower limit
to check for valid default_backlight setting. However some newer panels
can support even lower default settings

[why]
Need a helper function to check idle power is allowed
so that dc doesn't access any registers that are power-gated.
[how]
Implement helper function to check idle power optimization.
Enable a hook to check if detection is allowed.
V2:
Add function hooks for set and get idle states.
Check if function hook was properly initialized.

Currently there are separate but related checks:
* amdgpu_device_should_use_aspm()
* amdgpu_device_aspm_support_quirk()
* amdgpu_device_pcie_dynamic_switching_supported()
Simplify into checking whether DPM was enabled or not in the auto
case. This works because amdgpu_device_pcie_dynamic_switching_supported()
populates that value.

This reverts commit dc427a473e.
The change prevents migrating the entire range to VRAM because retry
fault restore_pages map the remaining system memory range to GPUs. It
will work correctly to submit together with partial mapping to GPU
patch later.

Pull EFI fixes from Ard Biesheuvel:
"The boot_params pointer fix uses a somewhat ugly extern struct
declaration but this will be cleaned up the next cycle.
- don't try to print warnings to the console when it is no longer

- fix theoretical memory leak in SSDT override handling
- make sure that the boot_params global variable is set before the
KASLR code attempts to hash it for 'randomness'
- avoid soft lockups in the memory acceptance code"
