There is a logic error in the error handler's labels.
ex/ The sysfs: is the last goto label in the normal code but
is the middle of error handler.  Rework the error handler.

cleanup: is the first error, so it's handler should be last.

interrupt: is the second error, it's handler is next.  interrupt:
handles the failure of amdgpu_ras_interrupt_add_hander() by
calling amdgpu_ras_interrupt_remove_handler().  This is wrong,
remove() assumes the interrupt has been setup, not torn down by
add().  Change the goto label to cleanup.

sysfs is the last error, it's handler should be first.  sysfs:
handles the failure of amdgpu_ras_sysfs_create() by calling
amdgpu_ras_sysfs_remove().  But when the create() fails there
is nothing added so there is nothing to remove.  This error
handler is not needed. Remove the error handler and change
goto label to interrupt.

Make it dev_dbg_once(), as it isn't something correctible during boot or

1. The infinite loop causing soft lock occurs on multiple amdgpu cards
   supporting ras feature.
2. This a workaround patch to fix 6492e1b0.
   It is valid for multiple amdgpu cards of the same type.
3. The root cause is that each GPU card device has a separate .ras_list
   link header, but the instance and linked list node of each ras block
   are unique. When each device is initialized, each ras instance will
   repeatedly add link node to the device every time. In this way, only
   the .ras_list of the last initialized device is completely correct.
   the .ras_list->prev and .ras_list->next of the device initialzied
   before can still point to the correct ras instance, but the prev
   pointer and next pointer of the pointed ras instance both point to
   the last initialized device's .ras_ list instead of the beginning
   .ras_ list. When using list_for_each_entry_safe searches for
   non-existent Ras nodes on devices other than the last device, the
   last ras instance next pointer cannot always be equal to the
   beginning .ras_list, so that the loop cannot be terminated, the
   program enters a infinite loop.
 BTW: Since the data and initialization process of each card are the same,
      the link list between ras instances will not be destroyed every time
      the device is initialized.

1. Define unified ops interface for each block.
2. Add ras_block_match function pointer in ops interface, each ras block can customize specail match function to identify itself.
3. Add amdgpu_ras_block_match_default new function. If a ras block doesn't define .ras_block_match, default execute amdgpu_ras_block_match_default to identify this ras block.
4. Define unified basic ras block data for each ras block.
5. Create dedicated amdgpu device ras block link list to manage all of the ras blocks.
6. Add amdgpu_ras_register_ras_block new function interface for each ras block to register itself to ras controlling block.

Those implementation details(whether swsmu supported, some ppt_funcs supported,
accessing internal statistics ...)should be kept internally. It's not a good

Do not allow exported amdgpu_vram_mgr_*() to accept
any ttm_resource_manager pointer. Also there is no need
to force other module to call a ttm function just to
eventually call vram_mgr functions.
