drm/amdgpu: Add sysfs interface for sdma reset mask

Add the sysfs interface for sdma:
sdma_reset_mask

The interface is read-only and show the resets supported by the IP.
For example, full adapter reset (mode1/mode2/BACO/etc),
soft reset, queue reset, and pipe reset.

V2: the sysfs node returns a text string instead of some flags (Christian)
v3: add a generic helper which takes the ring as parameter
   and print the strings in the order they are applied (Christian)

   check amdgpu_gpu_recovery  before creating sysfs file itself,
   and initialize supported_reset_types in IP version files (Lijo)
