Subject: [PATCH] drm/amdgpu: update ras capability's query based on mem ecc
configuration
RAS support capability needs to be updated on top of different memeory ECC
enablement, and remove redundant memory ecc check in gmc module for vega20 and
arcturus.
v2: check HBM ECC enablement and set ras mask accordingly.
v3: avoid to invoke atomfirmware interface to query twice.
