drm/amdgpu: Add gfx cp ecc error irq handling on gfx v11_0_3

Browse Source 
V2:
  Optimize gfx_v11_0_set_cp_ecc_error_state function.

V3:
  Define macro constant for me pipe instance address interval.

V5:
  Register and handle gfx cp ecc error irq on gfx v11_0_3.

V6:
  Remove invalid intermediate function call.
