drm/rockchip: dw-dp: Add HDCP function support

Browse Source

Adding HDCP1.3 and HDCP2.2 function support. For support
HDCP2.2, It also need prepare hdcp controller driver and
userspace host library.

Considering that HDCP2.2 is more secure than HDCP1.4, It
preferred to use HDCP2.2 if HDCP2.2 capable is be setup.
Only when the HDCP2.2 is not supported(or HDCP2.2 is failed)
and Content Type is Type0, HDCP1.3 will work.
