drm/bridge: analogix_dp: Fix incorrect operations with register ANALOGIX_DP_FUNC_EN_1

Browse source

Register ANALOGIX_DP_FUNC_EN_1(offset 0x18), Rockchip is different to
Exynos:

on Exynos edp phy,
BIT 7		MASTER_VID_FUNC_EN_N
BIT 6		reserved
BIT 5		SLAVE_VID_FUNC_EN_N

on Rockchip edp phy,
BIT 7		reserved
BIT 6		RK_VID_CAP_FUNC_EN_N
BIT 5		RK_VID_FIFO_FUNC_EN_N

So, we should do some private operations to Rockchip.
