Subject: drm/exynos: move to use request_irq by IRQF_NO_AUTOEN flag

From: Tian Tao <tiantao6@xxxxxxxxxxxxx>

commit a4e5eed2c6a689ef2b6ad8d7ae86665c69039379 upstream.

After this patch cbe16f35bee68 genirq: Add IRQF_NO_AUTOEN for
request_irq/nmi() is merged. request_irq() after setting
IRQ_NOAUTOEN as below

irq_set_status_flags(irq, IRQ_NOAUTOEN);
request_irq(dev, irq...);
can be replaced by request_irq() with IRQF_NO_AUTOEN flag.

v2:
Fix the problem of using wrong flags
