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. Move xgmi special error inject function from amdgpu_ras.c to xgmi block.
2. Support to use psp_ras_trigger_error as default error inject function in amdgpu_ras.c. If .ras_error_inject isn't defined in ras block, default error inject function will take effect.

1.Modify sdma block to fit for the unified ras block data and ops.
2.Change amdgpu_sdma_ras_funcs to amdgpu_sdma_ras, and the corresponding variable name remove _funcs suffix.
3.Remove the const flag of sdma ras variable so that sdma ras block can be able to be inserted into amdgpu device ras block link list.
4.Invoke amdgpu_ras_register_ras_block function to register sdma ras block into amdgpu device ras block link list.
5.Remove the redundant code about sdma in amdgpu_ras.c after using the unified ras block.
6.Fill unified ras block .name .block .ras_late_init and .ras_fini for all of sdma versions. If .ras_late_init and .ras_fini had been defined by the selected sdma version, the defined functions will take effect; if not defined, default fill them with amdgpu_sdma_ras_late_init and amdgpu_sdma_ras_fini.
