drm/rockchip: analogix_dp: Add support for RK3576
RK3576 integrates Analogix eDP 1.3 TX and Samsung combo PHY
hardware blocks that fully match the proven RK3588 design.
Add dedicated chip data table and device tree matching entry
to bring up basic eDP functionality for the RK3576 platform.
Support is limited to RGB output up to 4K@60Hz for now; audio,
PSR and other advanced eDP 1.3 features remain unvalidated.
