<content type='text'>
1.Modify gfx block to fit for the unified ras block data and ops.
2.Change amdgpu_gfx_ras_funcs to amdgpu_gfx_ras, and the corresponding variable name remove _funcs suffix.
3.Remove the const flag of gfx ras variable so that gfx 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 gfx ras block into amdgpu device ras block link list.
5.Remove the redundant code about gfx 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 gfx versions. If .ras_late_init and .ras_fini had been defined by the selected gfx version, the defined functions will take effect; if not defined, default fill with amdgpu_gfx_ras_late_init and amdgpu_gfx_ras_fini.

Those implementation details(whether swsmu supported, some ppt_funcs supported,
accessing internal statistics ...)should be kept internally. It's not a good
practice and even error prone to expose implementation details.

Currently AMDGPU_RING_PRIO_MAX is redefinition of a
max gfx hwip priority, this won't work well when we will
have a hwip with different set of priorities than gfx.
Also, HW ring priorities are different from ring priorities.

Create a global enum for ring priority levels which each
HWIP can use to define its own priority levels.

When connected to a host via xGMI, system fatal errors may trigger
warm reset, driver has no change to query edc status before reset.
Therefore in this case, driver should harvest previous error loging
registers during boot, instead of only resetting them.

v2:
1. IP's ras_manager object is created when its ras feature is enabled,
so change to query edc status after amdgpu_ras_late_init called

2. change to enable watchdog timer after finishing gfx edc init

SQ's watchdog timer monitors forward progress, a mask of which waves
caused the watchdog timeout is recorded into ras status registers and
then trigger a system fatal error event.

v2:
1. change *query_timeout_status to *query_sq_timeout_status.
2. move query_sq_timeout_status into amdgpu_ras_do_recovery.
3. add module parameters to enable/disable fatal error event and modify
