[PATCH v1 5/7] drm/bridge: analogix_dp: Simplify analogix_dp_config_interrupt()

[Damon Ding <damon.ding@rock-chips.com>]

Remove local COMMON_INT_MASK and INT_STA_MASK macros. 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
mask to initialize HPD interrupt state, removing duplicated register
handling.
