Add the HDCP QSEECOM header file as it contains definitions used
in client drivers such as the DisplayPort driver.
This implementation is based on a snapshot of the HDCP QSEECOM
module as of this commit 86411ada84786796 ("drm/msm/hdcp: Update
HDCP QSEECOM to start auth on user command") on kernel-4.19.
