drm/amd/amdgpu: Fix warnings in amdgpu_encoders.c

Fix below checkpatch warnings:

WARNING: Missing a blank line after declarations
+ struct amdgpu_connector *amdgpu_connector = to_amdgpu_connector(connector);
+ amdgpu_encoder->active_device = amdgpu_encoder->devices & amdgpu_connector->devices;

WARNING: Prefer 'unsigned int' to bare use of 'unsigned'
