Subject: [PATCH AUTOSEL 6.13 16/28] phy: rockchip: usbdp: Avoid call hpd_event_trigger in dp_phy_init

From: Andy Yan <andy.yan@...k-chips.com>

[ Upstream commit 28dc672a1a877c77b000c896abd8f15afcdc1b0c ]

Function rk_udphy_dp_hpd_event_trigger will set vogrf let it
trigger HPD interrupt to DP by Type-C. This configuration is only
required when the DP work in Alternate Mode, and called by
typec_mux_set. In standard DP mode, such settings will prevent
the DP from receiving HPD interrupts.
