Think this points to your problem, you must decide between mainline/actual kernel using
mesa3d/etnaviv configuration or freescale/nxp kernel using the vivante graphics stack...

From your provided config it is hard to judge which way your try...some etnaviv
options enabled some IMX/Vivante ones enabled... but the main point is
the selected kernel and kernel options, but your config points to private repo and
private config...., but from the selected/used kernel header version (4.9) I would
suspect an freescale/nxp kernel?

Peter
