Update simplefb to support the new preferred location for simplefb dt nodes
under /chosen.
Signed-off-by: Hans de Goede <hdegoede@xxxxxxxxxx>
--
Changes in v2:
-Make name array larger in case we ever encounter more then 10000 framebuffers
Changes in v3:
-Switch to for_each_child_of_node to loop over the nodes under chosen
Changes in v4:
-Wrap the chosen enumeration code in #ifdef CONFIG_OF, as simplefb is used on
non devicetree platforms too
-simplefb can only be built-in, so drop the module_exit function calling
platform_driver_unregister
