package/freescale-imx/imx-gpu-viv: make pkg-config fixups mutually exclusive
The IMX_GPU_VIV_FIXUP_PKGCONFIG fixup is defined conditionally
depending on the value of IMX_GPU_VIV_LIB_TARGET, which means that
obviously only one of the definitions is possible. Make this clear by
using a ifeq ... else ifeq ... else ifeq ... endif logic.
