drm/rockchip: dw_dp: Fix null-ptr-deref in dw_dp_remove()
Attempting to access driver data in the platform driver ->remove()
callback may lead to a null pointer dereference since there is no
guaranty that the component ->bind() callback invoking
platform_set_drvdata() was executed.
A common scenario is when Rockchip DRM driver didn't manage to run
component_bind_all() because of an (unrelated) error causing early
return from rockchip_drm_bind().
Drop the unnecessary call to platform_get_drvdata() and, instead,
reference the target device structure via platform_device.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
