ccimx6/6qp: imx-gst1.0-plugin: add missing symbol to fix compilation

This package depends on libg2d, and the latest version of this library's
sources for imx6 platforms are currently unavailable. Among other things, the
newer sources add a symbol needed by imx-gst1.0-plugin to compile, so this
patch manually adds the symbol as a macro in the package's source code.

+Subject: [PATCH] imx_2d_device_g2d: define a G2D_AMPHION_INTERLACED macro
+
+Currently, this symbol is not present in the libg2d used by imx6 platforms, so
+this is a workaround to get the package to compile.
