uboot-mediatek: add patch to allow accessing bootconf from Linux
Store selected boot configuration in '/chosen' node in device tree, so it can be accessed by Linux (and used for fine-tuning the FIT partition parser). Signed-off-by: Daniel Golle <daniel@makrotopia.org> (cherry picked from commit dfc3ea6810904f4f498d4a1304443c1a4c9f1e3c)

+It can be useful for the OS (Linux) to know which configuration has
+been chosen by U-Boot when launching a FIT image.
+Store the name of the FIT configuration node used in a new string
+attribute called 'bootconf' in the '/chosen' node in device tree.
