firmware: qcom: scm: Add HDCP Support
HDCP driver needs to check if secure environment supports HDCP. If it's supported, then it requires to program some registers through SCM. Add qcom_scm_hdcp_available and qcom_scm_hdcp_req to support these requirements. Signed-off-by: Jilai Wang <jilaiw@codeaurora.org> Signed-off-by: Kumar Gala <galak@codeaurora.org>
