[PATCH 2/2] drm/ingenic: depend on COMMON_CLK to fix compile tests

[Krzysztof Kozlowski]

The Ingenic DRM uses Common Clock Framework thus it cannot be built on
platforms without it (e.g. compile test on MIPS with RALINK and
SOC_RT305X):

    /usr/bin/mips-linux-gnu-ld: drivers/gpu/drm/ingenic/ingenic-drm-drv.o: in function `ingenic_drm_bind.isra.0':
    ingenic-drm-drv.c:(.text+0x1600): undefined reference to `clk_get_parent'
    /usr/bin/mips-linux-gnu-ld: ingenic-drm-drv.c:(.text+0x16b0): undefined reference to `clk_get_parent'
