Subject: drm/amdgpu: support B0&B1 external revision id for yellow carp
Git-commit: 53c2ff8bcb06acd07e24a62e7f5a0247bd7c6f67
Patch-mainline: v5.15
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225

B0 internal rev_id is 0x01, B1 internal rev_id is 0x02.
The external rev_id for B0 and B1 is 0x20.
The original expression is not suitable for B1.
