drm/amd: add AMDGPU_DEBUG_HIBERNATION_THAW_RESUME_GPU debug mask

Browse source

Kernel parameter `no_console_suspend` is required to capture all
hibernation kernel log via serial console. But when the parameter
is set, GPU will be resumed in thaw stage. This causes many issues
on alinux3 kernel.

Fix: add new debug mask `AMDGPU_DEBUG_HIBERNATION_THAW_RESUME_GPU` to
replace the check of `console_suspend_enabled` in thaw() callback.
User can enable it using `amdgpu.debug_mask=0x800`.
