[PATCH v6] drm/msm/dp: Always clear mask bits to disable interrupts at dp_ctrl_reset_irq_ctrl()

dp_catalog_ctrl_reset() will software reset DP controller. But it will not reset programmable registers to default value. DP driver still have to clear mask bits to interrupt status registers to disable interrupts after software reset of controller. At current implementation,
