[PATCH v4 09/10] drm/bridge: analogix_dp: Add support for RK3576

[Damon Ding]

Add RK3576_EDP device type entry and extend Rockchip check
to match existing hardware capabilities shared with RK3588.

Set identical maximum link rate and lane count parameters
for RK3576 eDP controller to reuse existing RK3588 config.
