Subject: [PATCH 5.19 14/38] drm/rockchip: vop2: Fix eDP/HDMI sync polarities

From: Sascha Hauer <s.hauer@...gutronix.de>

[ Upstream commit 35b513a74eabf09bd718e04fd9e62b09c022807f ]

The hsync/vsync polarities were not honoured for the eDP and HDMI ports.
Add the register settings to configure the polarities as requested by the
DRM_MODE_FLAG_PHSYNC/DRM_MODE_FLAG_PVSYNC flags.
