[PATCH v7 03/15] drm/bridge: analogix_dp: Add irq flag IRQF_NO_AUTOEN instead of calling disable_irq()

[Damon Ding]

The IRQF_NO_AUTOEN can be used for the drivers that don't want
interrupts to be enabled automatically via devm_request_threaded_irq().
Using this flag can provide be more robust compared to the way of
calling disable_irq() after devm_request_threaded_irq() without the
IRQF_NO_AUTOEN flag.
