drm/bridge: analogix_dp: set IRQ_NOAUTOEN to the irq flag

Browse Source 
The interrupt is requested before the device is powered on and
it's value in some cases cannot be reliable. It happens on some
devices that an interrupt is generated as soon as requested
before having the chance to disable the irq.
