package/kodi: remove imx support

https://git.buildroot.net/buildroot/commit/?id=266208972192f1e0869f89d7be941de6294a810a
broke imx support in Kodi because previously the G2D libraries were
part of the imx-gpu-viv package:

CMake Error at /usr/share/cmake-3.7/Modules/FindPackageHandleStandardArgs.cmake:138 (message):
  Could NOT find IMX (missing: G2D_LIBRARY)

Adjusting the Kodi package to use the imx-gpu-g2d as well still does
not provide a working build:

Although it might be possible to fix these bugs with something like

	#define DCIC_IOC_CONFIG_DCIC    _IO('D', 12)
	#define DCIC_IOC_START_VSYNC    _IO('D', 15)
	#define DCIC_IOC_STOP_VSYNC     _IO('D', 16)

as done in
https://raw.githubusercontent.com/LibreELEC/LibreELEC.tv/libreelec-7.0/projects/imx6/patches/kodi/imx6-jarvis.patch

we would still try to ride a dead horse. The upcoming Kodi version
18.0-Leia will remove imx support completely, see upstream PR 12990.
