drm/amdgpu: Update PTE flags with TF enabled
This patch updates the PTE flags when translate further (TF) is
enabled:
- With translate_further enabled, invalid PTEs can be 0. Reading
consecutive invalid PTEs as 0 is considered a fault. To prevent
this, ensure invalid PTEs have at least 1 bit set.
- The current invalid PTE flags settings to translate a retry fault
into a no-retry fault, doesn't work with TF enabled. As a result,
update invalid PTE flags settings which works for both TF enabled
and disabled case.
