Clean the interrupt status before enable interrupt
and set the vblank_disable_allowed to fix the issue.

MTK DRM driver didn't set the vblank_disable_allowed to
true, it cause that the irq_handler is called every
16.6 ms (every vblank) when the display didn't be updated.

To make sure that the first vblank IRQ after enabling
vblank isn't too short or immediate, we have to clear
the IRQ status before enable OVL interrupt.
