The function vc4_hdmi_connector_detect access its vc4_hdmi struct by dereferencing the pointer in the structure vc4_dev. This will cause some issues when we will have multiple HDMI controllers, so let's just use the local variable for now instead of dereferencing that pointer all the time, and we'll fix the local variable later.
