drm/amd/display: Add initialized-branch test for psp_set_srm

Browse source

Cover the initialized path of psp_set_srm() using the SR-IOV VF bypass so
psp_hdcp_invoke() is a no-op. The test asserts the SET_SRM command is
staged (cmd_id, srm_buf_size and the copied SRM bytes) and that response
validation fails on the zeroed reply, returning -EINVAL without updating
srm_version.
