drm/amdgpu/display: clean up hdcp workqueue handling
Use the existence of the workqueue itself to determine when to
enable HDCP features rather than sprinkling asic checks all over
the code. Also add a check for the existence of the hdcp
workqueue in the irq handling on the off chance we get and HPD
RX interrupt with the CP bit set. This avoids a crash if
the driver doesn't support HDCP for a particular asic.
