[PATCH 3/4] DRM: BRIDGE: TFP410: Fix logic to configured polled HPD

From: Michael Williamson <michael.williamson at criticallink.com>

The logic to configure polling (vs async/irq notification) of hot-plug
events was not correct.  If the connected bridge requires polling,
then inform the upstream bridge we also require polling.
