drm/i915/dp: Log the DPCD only if we have successfully retrieved one
Moving the DPCD just after a successful read will allow to:
- log all DPCD reads (eDP ones, changes signalled by HPD IRQ)
- don't log it if we haven't been able to read it
v2: Be sure to log the DPCD when a downstream port does not have HPD
support and the branch device asserts HPD (Jani Nikula)
