drm/verisilicon: vs_dc: Fix to disable interrupt on probe

There is a case where interrupt enable is set in decon req before
decon probe is completed. There is a problem that a kernel panic
occurs if an interrupt is executed before the decon is bound. Disable
interrupts before registering interrupts. Also, irq generated when the
interrupt state is disabled is ignored.
