Subject: [PATCH 5.14 049/125] drm/amdgpu: support B0&B1 external revision id for yellow carp

From: Aaron Liu <aaron.liu@....com>

commit 53c2ff8bcb06acd07e24a62e7f5a0247bd7c6f67 upstream.

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.

v2: squash in fix for display code (Alex)
