Analogix_dp driver acquires all its resources in the ->bind() callback,
what is a bit against the component driver based approach, where the
driver initialization is split into a probe(), where all resources are
gathered, and a bind(), where all objects are created and a compound
driver is initialized.
Extract all the resource related operations to analogix_dp_probe() and
analogix_dp_remove(), then call them before/after registration of the
device components from the main Exynos DP and Rockchip DP drivers. Also
move the plat_data initialization to the probe() to make it available for
the analogix_dp_probe() function.
This fixes the multiple calls to the bind() of the DRM compound driver
when the DP PHY driver is not yet loaded/probed:
