These constants are only used once inside this function and bring no reuse benefit. Replace open-coded register writes for COMMON_INT_MASK_1~3 with direct writel(0) calls. Leverage analogix_dp_unmute_hpd_interrupt() using the full HPD_IRQ_ALL mask to initialize HPD interrupt state, removing duplicated register handling.
