Subject: [PATCH] package/sunxi-mali-utgard: support the wayland driver

Add a choice to allow using the Wayland variant of the r6p2 Mali driver.
When selected, the package is marked as provider for libgbm as
libMali.so includes the symbols and a libgbm.so symlink is installed;
and both BR2_PACKAGE_HAS_{LIBGBM,LIBEGL_WAYLAND} are selected
accordingly.
