tegra : HDMI: hdmi hot plug detection modification
When tegra_dc_hdmi_detect is triggered with high HPD Interrupt,
but there's no previous trigger of low HPD interrupt,
by some specific HW design,
then, there's no switch change, no hotplug_handling is getting
called because 1=>1 change do nothing in switch_set_state.
Add this change for safe operation.
